Title
GLPI - Reports plugin for GLPI Reflected Cross-Site-Scripting (RXSS)
Summary
GLPI - Reports plugin for GLPI Reflected Cross-Site-Scripting (RXSS). Type 1: Reflected XSS (or Non-Persistent) - The server reads data directly from the HTTP request and reflects it back in the HTTP response. Reflected XSS exploits occur when an attacker causes a victim to supply dangerous content to a vulnerable web application, which is then reflected back to the victim and executed by the web browser. The most common mechanism for delivering malicious content is to include it as a parameter in a URL that is posted publicly or emailed directly to the victim. URLs constructed in this manner constitute the core of many phishing schemes, whereby an attacker convinces a victim to visit a URL that refers to a vulnerable site. After the site reflects the attacker's content back to the victim, the content is executed by the victim's browser.

CVE-2022-39207 (GCVE-0-2022-39207)

Vulnerability from cvelistv5 – Published: 2022-09-13 18:50 – Updated: 2025-04-22 17:21

Title
Persistent XSS in OneDev
Summary
Onedev is an open source, self-hosted Git Server with CI/CD and Kanban. During CI/CD builds, it is possible to save build artifacts for later retrieval. They can be accessed through OneDev's web UI after the successful run of a build. These artifact files are served by the webserver in the same context as the UI without any further restrictions. This leads to Cross-Site Scripting (XSS) when a user creates a build artifact that contains HTML. When accessing the artifact, the content is rendered by the browser, including any JavaScript that it contains. Since all cookies (except for the rememberMe one) do not set the HttpOnly flag, an attacker could steal the session of a victim and use it to impersonate them. To exploit this issue, attackers need to be able to modify the content of artifacts, which usually means they need to be able to modify a project's build spec. The exploitation requires the victim to click on an attacker's link. It can be used to elevate privileges by targeting admins of a OneDev instance. In the worst case, this can lead to arbitrary code execution on the server, because admins can create Server Shell Executors and use them to run any command on the server. This issue has been patched in version 7.3.0. Users are advised to upgrade. There are no known workarounds for this issue.

They can be accessed through OneDev\u0027s web UI after the successful run of a build. These artifact files are served by the webserver in the same context as the UI without any further restrictions. This leads to Cross-Site Scripting (XSS) when a user creates a build artifact that contains HTML. When accessing the artifact, the content is rendered by the browser, including any JavaScript that it contains. Since all cookies (except for the rememberMe one) do not set the HttpOnly flag, an attacker could steal the session of a victim and use it to impersonate them. To exploit this issue, attackers need to be able to modify the content of artifacts, which usually means they need to be able to modify a project\u0027s build spec. The exploitation requires the victim to click on an attacker\u0027s link. It can be used to elevate privileges by targeting admins of a OneDev instance. In the worst case, this can lead to arbitrary code execution on the server, because admins can create Server Shell Executors and use them to run any command on the server.

CVE-2022-39239 (GCVE-0-2022-39239)

Vulnerability from cvelistv5 – Published: 2022-09-23 07:55 – Updated: 2025-04-23 16:56

Title
nefly-ipx subject to Server-Side Request Forgery and Stored Cross-Site Scripting via Cache Poisoning and Improper Host Validation
Summary
netlify-ipx is an on-Demand image optimization for Netlify using ipx. In versions prior to 1.2.3, an attacker can bypass the source image domain allowlist by sending specially crafted headers, causing the handler to load and return arbitrary images. Because the response is cached globally, this image will then be served to visitors without requiring those headers to be set. XSS can be achieved by requesting a malicious SVG with embedded scripts, which would then be served from the site domain. Note that this does not apply to images loaded in `<img>` tags, as scripts do not execute in this context. The image URL can be set in the header independently of the request URL, meaning any site images that have not previously been cached can have their cache poisoned. This problem has been fixed in version 1.2.3. As a workaround, cached content can be cleared by re-deploying the site.

CVE-2022-39270 (GCVE-0-2022-39270)

Vulnerability from cvelistv5 – Published: 2022-10-06 00:00 – Updated: 2025-04-23 16:52

Title
Arbitrary HTML injection in table-of-contents theme component in DiscoTOC
Summary
DiscoTOC is a Discourse theme component that generates a table of contents for topics. Users that can create topics in TOC-enabled categories (and have sufficient trust level - configured in component's settings) are able to inject arbitrary HTML on that topic's page. The issue has been fixed on the `main` branch. Admins can update the theme component through the admin UI (Customize -> Themes -> Components -> DiscoTOC -> Check for Updates). Alternatively, admins can temporarily disable the DiscoTOC theme component.

Title
Stored Cross-Site Scripting Vulnerability In File Parameter in zoneminder
Summary
ZoneMinder is a free, open source Closed-circuit television software application The file parameter is vulnerable to a cross site scripting vulnerability (XSS) by backing out of the current "tr" "td" brackets. This then allows a malicious user to provide code that will execute when a user views the specific log on the "view=log" page. This vulnerability allows an attacker to store code within the logs that will be executed when loaded by a legitimate user. These actions will be performed with the permission of the victim. This could lead to data loss and/or further exploitation including account takeover. This issue has been addressed in versions `1.36.27` and `1.37.24`. Users are advised to upgrade. Users unable to upgrade should disable database logging.

Mitigation ID: MIT-4

Phase: Architecture and Design

Strategy: Libraries or Frameworks

Description:

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].
  • Examples of libraries and frameworks that make it easier to generate properly encoded output include Microsoft's Anti-XSS library, the OWASP ESAPI Encoding module, and Apache Wicket.
Mitigation

Phases: Implementation, Architecture and Design

Description:

  • Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages. Study all expected communication protocols and data representations to determine the required encoding strategies.
  • For any data that will be output to another web page, especially any data that was received from external inputs, use the appropriate encoding on all non-alphanumeric characters.
  • Parts of the same output document may require different encodings, which will vary depending on whether the output is in the:
  • etc. Note that HTML Entity Encoding is only appropriate for the HTML body.
  • Consult the XSS Prevention Cheat Sheet [REF-724] for more details on the types of encoding and escaping that are needed.
  • HTML body
  • Element attributes (such as src="XYZ")
  • URIs
  • JavaScript sections
  • Cascading Style Sheets and style property
Mitigation ID: MIT-6

Phases: Architecture and Design, Implementation

Strategy: Attack Surface Reduction

Description:

  • Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide data to the application. Remember that such inputs may be obtained indirectly through API calls.
Mitigation ID: MIT-15

Phase: Architecture and Design

Description:

  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
Mitigation ID: MIT-27

Phase: Architecture and Design

Strategy: Parameterization

Description:

  • If available, use structured mechanisms that automatically enforce the separation between data and code. These mechanisms may be able to provide the relevant quoting, encoding, and validation automatically, instead of relying on the developer to provide this capability at every point where output is generated.
Mitigation ID: MIT-30.1

Phase: Implementation

Strategy: Output Encoding

Description:

  • Use and specify an output encoding that can be handled by the downstream component that is reading the output. Common encodings include ISO-8859-1, UTF-7, and UTF-8. When an encoding is not specified, a downstream component may choose a different encoding, either by assuming a default encoding or automatically inferring which encoding is being used, which can be erroneous. When the encodings are inconsistent, the downstream component might treat some character or byte sequences as special, even if they are not special in the original encoding. Attackers might then be able to exploit this discrepancy and conduct injection attacks; they even might be able to bypass protection mechanisms that assume the original encoding is also being used by the downstream component.
  • The problem of inconsistent output encodings often arises in web pages. If an encoding is not specified in an HTTP header, web browsers often guess about which encoding is being used. This can open up the browser to subtle XSS attacks.
Mitigation ID: MIT-43

Phase: Implementation

Description:

  • With Struts, write all data from form beans with the bean's filter attribute set to true.
Mitigation ID: MIT-31

Phase: Implementation

Strategy: Attack Surface Reduction

Description:

  • To help mitigate XSS attacks against the user's session cookie, set the session cookie to be HttpOnly. In browsers that support the HttpOnly feature (such as more recent versions of Internet Explorer and Firefox), this attribute can prevent the user's session cookie from being accessible to malicious client-side scripts that use document.cookie. This is not a complete solution, since HttpOnly is not supported by all browsers. More importantly, XmlHttpRequest and other powerful browser technologies provide read access to HTTP headers, including the Set-Cookie header in which the HttpOnly flag is set.
Mitigation ID: MIT-5

Phase: Implementation

Strategy: Input Validation

Description:

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
  • When dynamically constructing web pages, use stringent allowlists that limit the character set based on the expected value of the parameter in the request. All input should be validated and cleansed, not just parameters that the user is supposed to specify, but all data in the request, including hidden fields, cookies, headers, the URL itself, and so forth. A common mistake that leads to continuing XSS vulnerabilities is to validate only fields that are expected to be redisplayed by the site. It is common to see data from the request that is reflected by the application server or the application that the development team did not anticipate. Also, a field that is not currently reflected may be used by a future developer. Therefore, validating ALL parts of the HTTP request is recommended.
  • Note that proper output encoding, escaping, and quoting is the most effective solution for preventing XSS, although input validation may provide some defense-in-depth. This is because it effectively limits what will appear in output. Input validation will not always prevent XSS, especially if you are required to support free-form text fields that could contain arbitrary characters. For example, in a chat application, the heart emoticon ("<3") would likely pass the validation step, since it is commonly used. However, it cannot be directly inserted into the web page because it contains the "<" character, which would need to be escaped or otherwise handled. In this case, stripping the "<" might reduce the risk of XSS, but it would produce incorrect behavior because the emoticon would not be recorded. This might seem to be a minor inconvenience, but it would be more important in a mathematical forum that wants to represent inequalities.
  • Even if you make a mistake in your validation (such as forgetting one out of 100 input fields), appropriate encoding is still likely to protect you from injection-based attacks. As long as it is not done in isolation, input validation is still a useful technique, since it may significantly reduce your attack surface, allow you to detect some attacks, and provide other security benefits that proper encoding does not address.
  • Ensure that you perform input validation at well-defined interfaces within the application. This will help protect the application even if a component is reused or moved elsewhere.
Mitigation ID: MIT-21

Phase: Architecture and Design

Strategy: Enforcement by Conversion

Description:

  • When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
Mitigation ID: MIT-29

Phase: Operation

Strategy: Firewall

Description:

  • Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].
Mitigation ID: MIT-16

Phases: Operation, Implementation

Strategy: Environment Hardening

Description:

  • When using PHP, configure the application so that it does not use register_globals. During implementation, develop the application so that it does not rely on this feature, but be wary of implementing a register_globals emulation that is subject to weaknesses such as CWE-95, CWE-621, and similar issues.
CAPEC-209: XSS Using MIME Type Mismatch

An adversary creates a file with scripting content but where the specified MIME type of the file is such that scripting is not expected. The adversary tricks the victim into accessing a URL that responds with the script file. Some browsers will detect that the specified MIME type of the file does not match the actual type of its content and will automatically switch to using an interpreter for the real content type. If the browser does not invoke script filters before doing this, the adversary's script may run on the target unsanitized, possibly revealing the victim's cookies or executing arbitrary script in their browser.

CAPEC-588: DOM-Based XSS

This type of attack is a form of Cross-Site Scripting (XSS) where a malicious script is inserted into the client-side HTML being parsed by a web browser. Content served by a vulnerable web application includes script code used to manipulate the Document Object Model (DOM). This script code either does not properly validate input, or does not perform proper output encoding, thus creating an opportunity for an adversary to inject a malicious script launch a XSS attack. A key distinction between other XSS attacks and DOM-based attacks is that in other XSS attacks, the malicious script runs when the vulnerable web page is initially loaded, while a DOM-based attack executes sometime after the page loads. Another distinction of DOM-based attacks is that in some cases, the malicious script is never sent to the vulnerable web server at all. An attack like this is guaranteed to bypass any server-side filtering attempts to protect users.

CAPEC-591: Reflected XSS

This type of attack is a form of Cross-Site Scripting (XSS) where a malicious script is "reflected" off a vulnerable web application and then executed by a victim's browser. The process starts with an adversary delivering a malicious script to a victim and convincing the victim to send the script to the vulnerable web application.

CAPEC-592: Stored XSS

An adversary utilizes a form of Cross-site Scripting (XSS) where a malicious script is persistently "stored" within the data storage of a vulnerable web application as valid input.

CAPEC-63: Cross-Site Scripting (XSS)

An adversary embeds malicious scripts in content that will be served to web browsers. The goal of the attack is for the target software, the client-side browser, to execute the script with the users' privilege level. An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute code and scripts. Web browsers, for example, have some simple security controls in place, but if a remote attacker is allowed to execute scripts (through injecting them in to user-generated content like bulletin boards) then these controls may be bypassed. Further, these attacks are very difficult for an end user to detect.

CAPEC-85: AJAX Footprinting

This attack utilizes the frequent client-server roundtrips in Ajax conversation to scan a system. While Ajax does not open up new vulnerabilities per se, it does optimize them from an attacker point of view. A common first step for an attacker is to footprint the target environment to understand what attacks will work. Since footprinting relies on enumeration, the conversational pattern of rapid, multiple requests and responses that are typical in Ajax applications enable an attacker to look for many vulnerabilities, well-known ports, network locations and so on. The knowledge gained through Ajax fingerprinting can be used to support other attacks, such as XSS.
