Published: 07 July 2022
Summary
CVE-2022-31854 is a high-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Codologic Codoforum. Its CVSS base score is 7.2 (High).
Operationally, ranked in the top 0.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
Codoforum version 5.1 contains an arbitrary file upload vulnerability that stems from insufficient validation on the logo change feature in the administrative interface. The flaw is tracked as CVE-2022-31854 and is classified under CWE-434, carrying a CVSS 3.1 score of 7.2 that reflects network-accessible exploitation requiring high privileges.
An authenticated administrator can upload a crafted file through the logo option and subsequently execute arbitrary code on the server, resulting in full remote code execution. Public exploit code demonstrating this authenticated RCE path has been released, confirming that an attacker with administrative credentials can achieve complete system compromise.
The EPSS score for the vulnerability currently stands at 0.8260 with a recorded peak of 0.8549, indicating sustained exploitation interest after disclosure. Public proof-of-concept materials, including a functional exploit script and detailed write-ups, are readily available, underscoring the need for immediate attention to any deployments still running the affected version.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring identifiable owners for portable devices reduces the attack surface for unrestricted uploads of dangerous file types via anonymous media.
Dangerous file uploads can be detonated in the chamber to determine malice before any production write or execution occurs.
Prevents unrestricted writing of arbitrary or malicious firmware by keeping hardware write-protect enabled except under tightly controlled manual procedures.
Scans files from external sources on download/open/execute, blocking unrestricted uploads of dangerous file types.
