CVE-2024-8088: Infinite loop when iterating over zip archive entry names from zipfile.Path

Noroxi assessment

Priority: Monitor (action score 34/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.2% (FIRST EPSS); higher than 69.9% 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. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: Python Software Foundation CPython 3.10.15, 3.11.10, 3.12.6; Azure Linux 3.0 ARM 2.16.1-7, 3.12.3-4; Azure Linux 3.0 x64 2.16.1-7, 3.12.3-4.

Low priority for now. Upgrade to Python Software Foundation CPython 3.10.15, 3.11.10, 3.12.6; Azure Linux 3.0 ARM 2.16.1-7, 3.12.3-4; Azure Linux 3.0 x64 2.16.1-7, 3.12.3-4 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

There is a HIGH severity vulnerability affecting the CPython "zipfile" module affecting "zipfile.Path". Note that the more common API "zipfile.ZipFile" class is unaffected. When iterating over names of entries in a zip archive (for example, methods of "zipfile.Path" like "namelist()", "iterdir()", etc) the process can be put into an infinite loop with a maliciously crafted zip archive. This defect applies when reading only metadata or extracting the contents of the zip archive. Programs that are not handling user-controlled zip archives are not affected.
