CVE-2024-4142NVD status: Deferred

An Improper input validation vulnerability that could potentially lead to privilege escalation…

CVE-2024-4142 is a critical-severity improper input validation vulnerability in Artifactory from Jfrog, with a CVSS 3.1 base score of 9.0 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 7.84.6, 7.77.11, 7.71.21 as the first without the flaw, so updating Artifactory to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.67% chance of exploitation within 30 days, higher than 52% of scored CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update Artifactory to 7.84.6 or 7.77.11 or 7.71.21 or 7.68.21, whichever matches your release line, or a later version.
  2. Read the advisory on jfrog.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

An Improper input validation vulnerability that could potentially lead to privilege escalation was discovered in JFrog Artifactory. Due to this vulnerability, users with low privileges may gain administrative access to the system. This issue can also be exploited in Artifactory platforms with anonymous access enabled.

The underlying weakness: Improper Input Validation

The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.

How developers prevent this class of flaw

  • Consider using language-theoretic security (LangSec) techniques that characterize inputs using a formal language and build recognizers for that language. This effectively requires parsing to be a distinct layer that effectively enforces a boundary between raw input and internal data representations, instead of allowing parser code to be scattered throughout the program, where it could be subject to errors or inconsistencies that create weaknesses.
  • Use an input validation framework such as Struts or the OWASP ESAPI Validation API. Note that using a framework does not automatically address all input validation problems; be mindful of weaknesses that could arise from misusing the framework itself (CWE-1173).
  • Understand all the potential areas where untrusted inputs can enter the product, including but not limited to: 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.
