Published: 18 December 2024
Summary
CVE-2023-34990 is a critical-severity Relative Path Traversal (CWE-23) vulnerability in Fortinet Fortiwlm. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 1.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
A relative path traversal vulnerability affects Fortinet FortiWLM versions 8.6.0 through 8.6.5 and 8.5.0 through 8.5.4. The flaw, tracked as CVE-2023-34990 and assigned CWE-23 and CWE-94, permits remote attackers to execute unauthorized code or commands by submitting specially crafted web requests to the affected wireless LAN management software.
Unauthenticated attackers with network access can exploit the issue without user interaction or credentials. Successful exploitation grants full control over the target system, including the ability to read, modify, or delete data and execute arbitrary commands, consistent with the CVSS 9.8 rating reflecting complete confidentiality, integrity, and availability impact.
The Fortinet advisory FG-IR-23-144 addresses the issue, though specific patch or workaround details are not enumerated in the supplied references. The EPSS score has remained stable at its peak value of 0.7287 with no indicated rise after disclosure.

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.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
