Summary

CVE-2025-2997 is a medium-severity SSRF (CWE-918) vulnerability in Zhangyanbo2007 Youkefu. Its CVSS base score is 5.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 39th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-4 (Information Flow Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-2997 is a server-side request forgery (SSRF) vulnerability, classified under CWE-918, affecting zhangyanbo2007 youkefu version 4.2.0. The flaw resides in an unknown function within the file /res/url, where manipulation of the "url" argument triggers the SSRF. Published on 2025-03-31, it has been rated critical with a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).

A remote attacker possessing low privileges (PR:L) can exploit this vulnerability over the network with low complexity and no user interaction required. Exploitation enables limited impacts on confidentiality, integrity, and availability (C:L/I:L/A:L) via SSRF, allowing the attacker to make unauthorized requests from the server.

VulDB advisories (ctiid.302046, id.302046, submit.524009) document the issue, while a GitHub repository at https://github.com/exp3n5ive/Vul/blob/main/youkefu/youkefu.pdf discloses a public exploit that may be used by attackers. No specific patches or mitigations are detailed in the provided references.

The exploit disclosure heightens the risk, as it is publicly available for potential weaponization.

Mitigating Controls (NIST 800-53 r5) AI

Information flow enforcement can restrict which destinations the server is allowed to contact on behalf of users.

Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.

Boundary protection limits the network reach of server-initiated requests even if SSRF occurs.
