CVE-2020-17405 (GCVE-0-2020-17405)

Vulnerability from cvelistv5 – Published: 2020-09-01 18:00 – Updated: 2024-08-04 13:53
VLAI
Summary
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Senstar Symphony 7.3.2.2. Authentication is not required to exploit this vulnerability. The specific flaw exists within the SSOAuth process. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-10980.
Severity
8.8 (High)

Title
Deserialization flaw in EOL Tapestry 4.
Summary
A Java Serialization vulnerability was found in Apache Tapestry 4. Apache Tapestry 4 will attempt to deserialize the "sp" parameter even before invoking the page's validate method, leading to deserialization without authentication. Apache Tapestry 4 reached end of life in 2008 and no update to address this issue will be released. Apache Tapestry 5 versions are not vulnerable to this issue. Users of Apache Tapestry 4 should upgrade to the latest Apache Tapestry 5 version.
Severity

CVE-2020-27868 (GCVE-0-2020-27868)

Vulnerability from cvelistv5 – Published: 2021-02-11 23:35 – Updated: 2024-08-04 16:25
VLAI
Summary
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Qognify Ocularis 5.9.0.395. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of serialized objects provided to the EventCoordinator endpoint. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-11257.

CVE-2020-36727 (GCVE-0-2020-36727)

Vulnerability from cvelistv5 – Published: 2023-06-07 01:51 – Updated: 2026-04-08 17:27
VLAI
Title
Newsletter Manager <= 1.5.1 - Insecure Deserialization
Summary
The Newsletter Manager plugin for WordPress is vulnerable to insecure deserialization in versions up to, and including, 1.5.1. This is due to unsanitized input from the 'customFieldsDetails' parameter being passed through a deserialization function. This potentially makes it possible for unauthenticated attackers to inject a serialized PHP object.
Severity

Mitigation

Phases: Architecture and Design, Implementation

Description:

  • If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
Mitigation

Phase: Implementation

Description:

  • When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
Mitigation

Phase: Implementation

Description:

  • Explicitly define a final object() to prevent deserialization.
Mitigation

Phases: Architecture and Design, Implementation

Description:

  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
Mitigation

Phase: Implementation

Description:

  • Avoid having unnecessary types or gadgets (a sequence of instances and method invocations that can self-execute during the deserialization process, often found in libraries) available that can be leveraged for malicious ends. This limits the potential for unintended or unauthorized types and gadgets to be leveraged by the attacker. Add only acceptable classes to an allowlist. Note: new gadgets are constantly being discovered, so this alone is not a sufficient mitigation.
Mitigation

Phases: Architecture and Design, Implementation

Description:

  • Employ cryptography of the data or code for protection. However, it's important to note that it would still be client-side security. This is risky because if the client is compromised then the security implemented on the client (the cryptography) can be bypassed.
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].
CAPEC-586: Object Injection

An adversary attempts to exploit an application by injecting additional, malicious content during its processing of serialized objects. Developers leverage serialization in order to convert data or state into a static, binary format for saving to disk or transferring over a network. These objects are then deserialized when needed to recover the data/state. By injecting a malformed object into a vulnerable application, an adversary can potentially compromise the application by manipulating the deserialization process. This can result in a number of unwanted outcomes, including remote code execution.
