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

CVE-2024-57546 is a vulnerability in CMSimple version 5.16 that enables a remote attacker to obtain sensitive information by sending a crafted script to the validate link function. Classified under CWE-922, it carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), reflecting high confidentiality impact accessible over the network with low attack complexity, no privileges, and no user interaction required.

A remote unauthenticated attacker can exploit this issue by targeting the validate link function with a malicious script, leading to unauthorized disclosure of sensitive information. The CVSS vector underscores its ease of exploitation from external networks without authentication or special conditions.

Research details on the vulnerability, including analysis of the validate links SSRF behavior, are documented in GitHub references such as https://gist.github.com/h4ckr4v3n/afbb87b5a05f283dbee705709c2769eb and https://github.com/h4ckr4v3n/cmsimple5.16_research/blob/main/CMSimple%205.16%20Validate%20links%20SSRF.md.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces approved authorizations for logical access to stored information, directly stopping unauthorized read/write.

SC-28 Protection of Information at Rest good match

Requires protection of confidentiality/integrity for information at rest, directly addressing insecure storage.

AC-6 Least Privilege good match

Limits privileges so only authorized accesses to sensitive stored data are permitted.

AC-16 Security and Privacy Attributes partial match

Associates security attributes with information to support proper access decisions on storage.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-05 mostly match
prevents

Enforces least-privilege permissions and authorization reviews that limit read/write access to stored sensitive data.

PR.DS-01 mostly match
prevents

Directly protects data-at-rest confidentiality via encryption or access controls that prevent unauthorized reads.
