MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1552 Unsecured Credentials Credential Access
Adversaries may search compromised systems to find and obtain insecurely stored credentials.
Why these techniques?

Vulnerability in public-facing wwwupdate.cgi endpoint exposes session tokens in plaintext URLs (CWE-598), directly enabling remote exploitation of the web app (T1190) and access to unsecured credentials/tokens (T1552) for session hijacking.

Confidence: MEDIUM · MITRE ATT&CK Enterprise v18.1

NVD Description

An unauthenticated remote attacker can obtain valid session tokens because they are exposed in plaintext within the URL parameters of the wwwupdate.cgi endpoint in UBR.

Deeper analysisAI

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.
