CVE-2025-42620 (GCVE-0-2025-42620)
Vulnerability from nvd – Published: 2025-12-08 12:15 – Updated: 2025-12-08 12:27
VLAI
Title
CSRF vulnerability in CIRCL Vulnerability-Lookup
Summary
In affected versions, vulnerability-lookup handled user-controlled
content in comments and bundles in an unsafe way, which could lead to
stored Cross-Site Scripting (XSS).
On the backend, the related_vulnerabilities field of bundles accepted
arbitrary strings without format validation or proper sanitization. On
the frontend, comment and bundle descriptions were converted from
Markdown to HTML and then injected directly into the DOM using string
templates and innerHTML. This combination allowed an attacker who could
create or edit comments or bundles to store crafted HTML/JavaScript
payloads which would later be rendered and executed in the browser of
any user visiting the affected profile page (user.html).
This issue affects Vulnerability-Lookup: before 2.18.0.

CVE-2025-42616 (GCVE-0-2025-42616)
Vulnerability from nvd – Published: 2025-12-08 12:09 – Updated: 2025-12-08 14:46
VLAI
Title
CSRF vulnerability in CIRCL Vulnerability-Lookup
Summary
Some endpoints in vulnerability-lookup that modified
application state (e.g. changing database entries, user data,
configurations, or other privileged actions) may have been accessible
via HTTP GET requests without requiring a CSRF token. This flaw leaves
the application vulnerable to Cross-Site Request Forgery (CSRF) attacks:
an attacker who tricks a logged-in user into visiting a malicious
website could cause the user’s browser to issue GET requests that
perform unintended state-changing operations in the context of their
authenticated session.
Because the server would treat these GET requests as valid (since no
CSRF protection or POST method enforcement was in place), the attacker
could exploit this to escalate privileges, change settings, or carry out
other unauthorized actions without needing the user’s explicit consent
or awareness.
The fix ensures that all state-changing endpoints now require HTTP POST
requests and include a valid CSRF token. This enforces that state
changes cannot be triggered by arbitrary cross-site GET requests. This issue affects Vulnerability-Lookup: before 2.18.0.

CVE-2025-42615 (GCVE-0-2025-42615)
Vulnerability from nvd – Published: 2025-12-08 12:01 – Updated: 2025-12-08 20:10
VLAI
Title
Improper Restriction of Excessive Authentication Attempts vulnerability in CIRCL Vulnerability-Lookup
Summary
In affected versions, vulnerability-lookup did not track or limit failed
One-Time Password (OTP) attempts during Two-Factor Authentication (2FA)
verification. An attacker who already knew or guessed a valid username
and password could submit an arbitrary number of OTP codes without
causing the account to be locked or generating any specific alert for
administrators.
This lack of rate-limiting and lockout on OTP failures significantly
lowers the cost of online brute-force attacks against 2FA codes and
increases the risk of successful account takeover, especially if OTP
entropy is reduced (e.g. short numeric codes, user reuse, or predictable
tokens). Additionally, administrators had no direct visibility into
accounts experiencing repeated 2FA failures, making targeted attacks
harder to detect and investigate.
The patch introduces a persistent failed_otp_attempts counter on user
accounts, locks the user after 5 invalid OTP submissions, resets the
counter on successful verification, and surfaces failed 2FA attempts in
the admin user list. This enforces an account lockout policy for OTP
brute-force attempts and improves monitoring capabilities for suspicious
2FA activity.This issue affects Vulnerability-Lookup: before 2.18.0.

CVE-2025-60249 (GCVE-0-2025-60249)
Vulnerability from nvd – Published: 2025-09-25 00:00 – Updated: 2025-09-26 17:44
VLAI
Summary
vulnerability-lookup 2.16.0 allows XSS in bundle.py, comment.py, and user.py, by a user on a vulnerability-lookup instance who can add bundles, comments, or sightings. A cross-site scripting (XSS) vulnerability was discovered in the handling of user-supplied input in the Bundles, Comments, and Sightings components. Untrusted data was not properly sanitized before being rendered in templates and tables, which could allow attackers to inject arbitrary JavaScript into the application. The issue was due to unsafe use of innerHTML and insufficient validation of dynamic URLs and model fields. This vulnerability has been fixed by escaping untrusted data, replacing innerHTML assignments with safer DOM methods, encoding URLs with encodeURIComponent, and improving input validation in the affected models.

A cross-site scripting (XSS) vulnerability was discovered in the handling of user-supplied input in the Bundles, Comments, and Sightings components. Untrusted data was not properly sanitized before being rendered in templates and tables, which could allow attackers to inject arbitrary JavaScript into the application. The issue was due to unsafe use of innerHTML and insufficient validation of dynamic URLs and model fields. This vulnerability has been fixed by escaping untrusted data, replacing innerHTML assignments with safer DOM methods, encoding URLs with encodeURIComponent, and improving input validation in the affected models."

Title
CSRF vulnerability in CIRCL Vulnerability-Lookup
Summary
In affected versions, vulnerability-lookup handled user-controlled
content in comments and bundles in an unsafe way, which could lead to
stored Cross-Site Scripting (XSS).
On the backend, the related_vulnerabilities field of bundles accepted
arbitrary strings without format validation or proper sanitization. On
the frontend, comment and bundle descriptions were converted from
Markdown to HTML and then injected directly into the DOM using string
templates and innerHTML. This combination allowed an attacker who could
create or edit comments or bundles to store crafted HTML/JavaScript
payloads which would later be rendered and executed in the browser of
any user visiting the affected profile page (user.html).
This issue affects Vulnerability-Lookup: before 2.18.0.

Title
CSRF vulnerability in CIRCL Vulnerability-Lookup
Summary
Some endpoints in vulnerability-lookup that modified
application state (e.g. changing database entries, user data,
configurations, or other privileged actions) may have been accessible
via HTTP GET requests without requiring a CSRF token. This flaw leaves
the application vulnerable to Cross-Site Request Forgery (CSRF) attacks:
an attacker who tricks a logged-in user into visiting a malicious
website could cause the user’s browser to issue GET requests that
perform unintended state-changing operations in the context of their
authenticated session.
Because the server would treat these GET requests as valid (since no
CSRF protection or POST method enforcement was in place), the attacker
could exploit this to escalate privileges, change settings, or carry out
other unauthorized actions without needing the user’s explicit consent
or awareness.
The fix ensures that all state-changing endpoints now require HTTP POST
requests and include a valid CSRF token. This enforces that state
changes cannot be triggered by arbitrary cross-site GET requests. This issue affects Vulnerability-Lookup: before 2.18.0.

CVE-2025-42615 (GCVE-0-2025-42615)
Vulnerability from cvelistv5 – Published: 2025-12-08 12:01 – Updated: 2025-12-08 20:10

Title
Improper Restriction of Excessive Authentication Attempts vulnerability in CIRCL Vulnerability-Lookup
Summary
In affected versions, vulnerability-lookup did not track or limit failed
One-Time Password (OTP) attempts during Two-Factor Authentication (2FA)
verification. An attacker who already knew or guessed a valid username
and password could submit an arbitrary number of OTP codes without
causing the account to be locked or generating any specific alert for
administrators.
This lack of rate-limiting and lockout on OTP failures significantly
lowers the cost of online brute-force attacks against 2FA codes and
increases the risk of successful account takeover, especially if OTP
entropy is reduced (e.g. short numeric codes, user reuse, or predictable
tokens). Additionally, administrators had no direct visibility into
accounts experiencing repeated 2FA failures, making targeted attacks
harder to detect and investigate.
The patch introduces a persistent failed_otp_attempts counter on user
accounts, locks the user after 5 invalid OTP submissions, resets the
counter on successful verification, and surfaces failed 2FA attempts in
the admin user list. This enforces an account lockout policy for OTP
brute-force attempts and improves monitoring capabilities for suspicious
2FA activity.This issue affects Vulnerability-Lookup: before 2.18.0.

CVE-2025-60249 (GCVE-0-2025-60249)
Vulnerability from cvelistv5 – Published: 2025-09-25 00:00 – Updated: 2025-09-26 17:44
VLAI
Summary
vulnerability-lookup 2.16.0 allows XSS in bundle.py, comment.py, and user.py, by a user on a vulnerability-lookup instance who can add bundles, comments, or sightings. A cross-site scripting (XSS) vulnerability was discovered in the handling of user-supplied input in the Bundles, Comments, and Sightings components. Untrusted data was not properly sanitized before being rendered in templates and tables, which could allow attackers to inject arbitrary JavaScript into the application. The issue was due to unsafe use of innerHTML and insufficient validation of dynamic URLs and model fields. This vulnerability has been fixed by escaping untrusted data, replacing innerHTML assignments with safer DOM methods, encoding URLs with encodeURIComponent, and improving input validation in the affected models.

Title
Insufficient sanitization of bundle metadata (available to admin only) and unsafe DOM construction allows stored XSS
Summary
In affected versions, vulnerability-lookup handled user-controlled content in comments and bundles in an unsafe way, which could lead to stored Cross-Site Scripting (XSS).
On the backend, the related_vulnerabilities field of bundles accepted arbitrary strings without format validation or proper sanitization. On the frontend, comment and bundle descriptions were converted from Markdown to HTML and then injected directly into the DOM using string templates and innerHTML. This combination allowed an attacker who could create or edit comments or bundles to store crafted HTML/JavaScript payloads which would later be rendered and executed in the browser of any user visiting the affected profile page (user.html).

Title
Missing CSRF protection on state-changing endpoints in Vulnerability-Lookup, potential cross-site request forgery (CSRF)
Summary
Before the fix, some endpoints in vulnerability-lookup that modified application state (e.g. changing database entries, user data, configurations, or other privileged actions) may have been accessible via HTTP GET requests without requiring a CSRF token. This flaw leaves the application vulnerable to Cross-Site Request Forgery (CSRF) attacks: an attacker who tricks a logged-in user into visiting a malicious website could cause the user’s browser to issue GET requests that perform unintended state-changing operations in the context of their authenticated session.
Because the server would treat these GET requests as valid (since no CSRF protection or POST method enforcement was in place), the attacker could exploit this to escalate privileges, change settings, or carry out other unauthorized actions without needing the user’s explicit consent or awareness.
The fix ensures that all state-changing endpoints now require HTTP POST requests and include a valid CSRF token. This enforces that state changes cannot be triggered by arbitrary cross-site GET requests.

Vulnerability from gna-1 – Published: 2025-12-08 10:11 – Updated: 2025-12-08 12:12

Title
Vulnerability-lookup did not track or limit failed One-Time Password (OTP) attempts during Two-Factor Authentication (2FA) verification.
Summary
In affected versions, vulnerability-lookup did not track or limit failed One-Time Password (OTP) attempts during Two-Factor Authentication (2FA) verification. An attacker who already knew or guessed a valid username and password could submit an arbitrary number of OTP codes without causing the account to be locked or generating any specific alert for administrators.
This lack of rate-limiting and lockout on OTP failures significantly lowers the cost of online brute-force attacks against 2FA codes and increases the risk of successful account takeover, especially if OTP entropy is reduced (e.g. short numeric codes, user reuse, or predictable tokens). Additionally, administrators had no direct visibility into accounts experiencing repeated 2FA failures, making targeted attacks harder to detect and investigate.
The patch introduces a persistent failed_otp_attempts counter on user accounts, locks the user after 5 invalid OTP submissions, resets the counter on successful verification, and surfaces failed 2FA attempts in the admin user list. This enforces an account lockout policy for OTP brute-force attempts and improves monitoring capabilities for suspicious 2FA activity.

Title
XSS in Comments, Bundles, and Sightings component of vulnerability-lookup
Summary
A cross-site scripting (XSS) vulnerability was discovered in the handling of user-supplied input in the Comments, Bundles, and Sightings components. Untrusted data was not properly sanitized before being rendered in templates and tables, which could allow attackers to inject arbitrary JavaScript into the application. The issue was due to unsafe use of innerHTML and insufficient validation of dynamic URLs and model fields. This vulnerability has been fixed by escaping untrusted data, replacing innerHTML assignments with safer DOM methods, encoding URLs with encodeURIComponent, and improving input validation in the affected models.
