Operationally, exploitation aligns with the MITRE ATT&CK technique LSASS Memory (T1003.001); ranked in the top 11% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
rconfig version 3.9.4 contains a server-side request forgery vulnerability in the path parameter of /ajaxGetFileByPath.php. The flaw, tracked as CVE-2023-39110 and assigned CWE-918, permits an authenticated user to supply crafted URLs that cause the application to issue arbitrary requests to internal or external resources. It received a CVSS 3.1 score of 8.8 reflecting network attack vector, low complexity, and high impact across confidentiality, integrity, and availability.
An authenticated attacker with network access can exploit the issue without user interaction to reach otherwise inaccessible systems, retrieve sensitive data, or abuse the server as a proxy for further attacks. The EPSS score stands at 0.8015 with an identical recorded peak, indicating sustained exploitation interest since disclosure.
Public references consist of technical write-ups hosted on GitHub that demonstrate the request forgery but contain no official vendor guidance on patches or configuration changes.
