CVE-2024-8517: SPIP Bigup Multipart File Upload OS Command Injection

Noroxi assessment

Priority: This week (action score 67/100)

  • A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 94.6% (FIRST EPSS); higher than 99.8% 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: spip (Debian:13) 4.3.2+dfsg-1.

Don’t wait for the next maintenance window. Upgrade to spip (Debian:13) 4.3.2+dfsg-1 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

SPIP before 4.3.2, 4.2.16, and 4.1.18 is vulnerable to a command injection issue. A remote and unauthenticated attacker can execute arbitrary operating system commands by sending a crafted multipart file upload HTTP request.
