CVE-2024-50602: An issue was discovered in libexpat before 2.6.4.

Noroxi assessment

Priority: Monitor (action score 23/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.1% (FIRST EPSS); higher than 66% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: Azure Linux 3.0 ARM 2.6.3-2; Azure Linux 3.0 x64 2.6.3-2; CBL Mariner 2.0 ARM 2.6.3-2.

Low priority for now. Upgrade to Azure Linux 3.0 ARM 2.6.3-2; Azure Linux 3.0 x64 2.6.3-2; CBL Mariner 2.0 ARM 2.6.3-2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

An issue was discovered in libexpat before 2.6.4. There is a crash within the XML_ResumeParser function because XML_StopParser can stop/suspend an unstarted parser.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
