Common Weakness Enumeration
CWE-917
AllowedImproper 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.
177 vulnerabilities reference this CWE, most recent first.

Summary
Incomplete fix for Apache Log4j vulnerability
Details
Impact
The fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-default configurations. This could allow attackers with control over Thread Context Map (MDC) input data when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input data using a JNDI Lookup pattern resulting in a remote code execution (RCE) attack.
Affected packages
Only the org.apache.logging.log4j:log4j-core package is directly affected by this vulnerability. The org.apache.logging.log4j:log4j-api should be kept at the same version as the org.apache.logging.log4j:log4j-core package to ensure compatability if in use.
Mitigation
Log4j 2.16.0 fixes this issue by removing support for message lookup patterns and disabling JNDI functionality by default. This issue can be mitigated in prior releases (< 2.16.0) by removing the JndiLookup class from the classpath (example: zip -q -d log4j-core-*.jar org/apache/logging/log4j/core/lookup/JndiLookup.class).
Log4j 2.15.0 restricts JNDI LDAP lookups to localhost by default. Note that previous mitigations involving configuration such as to set the system property log4j2.formatMsgNoLookups to true do NOT mitigate this specific vulnerability.

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".
