Enterprise Server: Improper Neutralization of Special Elements used in a Command

CVE-2024-1372 is a critical-severity improper neutralization of special elements used in a command vulnerability in Enterprise Server from GitHub, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists versions 3.8.15, 3.9.10, 3.10.7 as the first without the flaw, so updating Enterprise Server to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 2.27% chance of exploitation within 30 days, higher than 83% of scored CVEs.

Official description

A command injection vulnerability was identified in GitHub Enterprise Server that allowed an attacker with an editor role in the Management Console to gain admin SSH access to the appliance when configuring SAML settings. Exploitation of this vulnerability required access to the GitHub Enterprise Server instance and access to the Management Console with the editor role. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.12 and was fixed in versions 3.11.5, 3.10.7, 3.9.10, and 3.8.15. This vulnerability was reported via the GitHub Bug Bounty program https://bounty.github.com .

The underlying weakness: Improper Neutralization of Special Elements used in a Command

The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.

How developers prevent this class of flaw

  • If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • If possible, ensure that all external commands called from the program are statically created.
  • Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
