Common Weakness Enumeration

CWE-917

Allowed

Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection')

Abstraction: Base · Status: Incomplete

The product constructs all or part of an expression language (EL) statement in a framework such as a Java Server Page (JSP) using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended EL statement before it is executed.

175 vulnerabilities reference this CWE, most recent first.

Details

Voltronic Power ViewPower Pro Expression Language Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Voltronic Power ViewPower Pro. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the Struts2 dependency. The issue results from the use of a library that is vulnerable to expression language injection. An attacker can leverage this vulnerability to execute code in the context of LOCAL SERVICE. Was ZDI-CAN-22095.

Details

In affected versions of Confluence Server and Data Center, an OGNL injection vulnerability exists that would allow an authenticated user, and in some instances an unauthenticated user, to execute arbitrary code on a Confluence Server or Data Center instance. The vulnerable endpoints can be accessed by a non-administrator user or unauthenticated user if ‘Allow people to sign up to create their account’ is enabled. To check whether this is enabled go to COG > User Management > User Signup Options. The affected versions are before version 6.13.23, from version 6.14.0 before 7.4.11, from version 7.5.0 before 7.11.6, and from version 7.12.0 before 7.12.5.

Vulnerability from github – Published: 2022-12-13 17:13 – Updated: 2024-10-29 14:59
VLAI
Summary
TYPO3 CMS vulnerable to Sensitive Information Disclosure via YAML Placeholder Expressions in Site Configuration
Details

CVSS: CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:L/A:L/E:F/RL:O/RC:C (5.3)

Problem

Due to the lack of handling user-submitted YAML placeholder expressions in the site configuration backend module, attackers could expose sensitive internal information, such as system configuration or HTTP request messages of other website visitors.

A valid backend user account having administrator privileges is needed to exploit this vulnerability.

Solution

Update to TYPO3 versions 9.5.38 ELTS, 10.4.33, 11.5.20, 12.1.1 that fix the problem described above.

Credits

Thanks to TYPO3 core & security team member Oliver Hader who reported and fixed the issue.

Mitigation
Architecture and Design

Avoid adding user-controlled data into an expression interpreter when possible.

Mitigation
Implementation
  • If user-controlled data must be added to an expression interpreter, one or more of the following should be performed:
  • Validate that the user input will not evaluate as an expression
  • Encode the user input in a way that ensures it is not evaluated as an expression
Mitigation
System Configuration Operation

The framework or tooling might allow the developer to disable or deactivate the processing of EL expressions, such as setting the isELIgnored attribute for a JSP page to "true".

No CAPEC attack patterns related to this CWE.
