CVE-2025-58159 — WeGIA Authenticated Arbitrary File Upload Leading To Remote Code Execution (RCE)

WeGIA is a Web manager for charitable institutions. Prior to version 3.4.11, a remote code execution vulnerability was identified, caused by improper validation of uploaded files. The application allows an attacker to upload files with arbitrary filenames, including those with a .php extension. Because the uploaded file is written directly to disk without adequate sanitization or extension restrictions, a spreadsheet file followed by PHP code can be uploaded and executed on the server, leading to arbitrary code execution. This is due to insufficient mitigation of CVE-2025-22133. This issue has been patched in version 3.4.11.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.8% (30-day exploitation probability)+8
Technical severity (high)+6
CISA SSVC: exploitation "poc"+5
Automatable exploitation (SSVC)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (LabRedesCefetRJ WeGIA, Wegia Wegia).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes matching the vulnerability class (file handling), errors and authentication anomalies.

What should defenders know first?

CVE-2025-58159 is "WeGIA Authenticated Arbitrary File Upload Leading To Remote Code Execution (RCE)", rated High. It affects WeGIA (LabRedesCefetRJ); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 8.8 describes technical severity. EPSS 0.76% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
