CVE-2024-11680: ProjectSend Unauthenticated Configuration Modification

Noroxi assessment

Priority: Now (action score 97/100)

  • CISA has confirmed exploitation in the wild (Dec 3, 2024). Remediation deadline for US federal agencies: Dec 24, 2024.
  • A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 91.8% (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.
  • No fixed version is recorded, but the references include a patch (commit or PR) link.

Patch today or shut off access. See the fix and affected versions sections below.

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 · CISA KEV · FIRST EPSS

ProjectSend versions prior to r1720 are affected by an improper authentication vulnerability. Remote, unauthenticated attackers can exploit this flaw by sending crafted HTTP requests to options.php, enabling unauthorized modification of the application's configuration. Successful exploitation allows attackers to create accounts, upload webshells, and embed malicious JavaScript.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Dec 3, 2024. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Dec 24, 2024.
