This vulnerability allows remote attackers to disclose sensitive information on affected installations of Netatalk. Authentication is not required to exploit this vulnerability. The specific flaw exists within the getdirparams method. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-15830.

Detection & IOCsextracted from sources · hover to see the quote

  • The vulnerable code path is within the `getdirparams` method in Netatalk; monitor or audit calls to this function for out-of-bounds read conditions triggered by unauthenticated remote input.
  • No authentication is required to trigger this vulnerability; any unauthenticated AFP/Netatalk network traffic targeting the getdirparams code path should be treated as suspicious.
  • This vulnerability can be chained with other bugs to achieve remote code execution as root; treat any Netatalk exploitation attempt as a potential privilege escalation chain.
  • ·Debian bullseye fix is available; ensure Netatalk is updated to at least 3.1.12~ds-8+deb11u1 on bullseye systems.
  • ·Debian forky, sid, and trixie fix is available; ensure Netatalk is updated to at least 3.1.13~ds-1 on those systems.
