The strongest mitigations our analysis identified map to SC-8 (Transmission Confidentiality and Integrity) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

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

CVE-2025-41772 affects the UBR software, specifically the wwwupdate.cgi endpoint, where valid session tokens are exposed in plaintext within URL parameters. This vulnerability, published on 2026-03-09, stems from CWE-598 (use of GET request method with sensitive query strings) and 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), indicating high confidentiality impact with low attack complexity and no privileges required.

An unauthenticated remote attacker can exploit this vulnerability over the network by accessing or intercepting URLs that include the wwwupdate.cgi endpoint, allowing them to obtain valid session tokens directly from the plaintext parameters.

SC-8 Transmission Confidentiality and Integrity partial match

Requiring confidentiality and integrity protection for transmitted data reduces exposure of sensitive query parameters even though the control does not forbid placing secrets in URLs.
