Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SC-23 Session Authenticity good match

prevent

SC-23 requires mechanisms to protect the authenticity of communications sessions, such as anti-CSRF tokens, directly addressing the lack of CSRF protection in Teedy.

SI-2 Flaw Remediation good match

prevent

SI-2 mandates identification, reporting, and timely correction of system flaws, comprehensively mitigating this CSRF vulnerability through patching or code remediation.

RA-5 Vulnerability Monitoring and Scanning partial match

detect

RA-5 requires vulnerability scanning that would identify the CSRF flaw in Teedy during assessments, enabling proactive remediation.

Why these techniques?

CVE-2024-54851 is a CSRF vulnerability in the public-facing Teedy web application, enabling exploitation to perform unauthorized state-changing actions on behalf of authenticated users.

NVD Description

Teedy <= 1.12 is vulnerable to Cross Site Request Forgery (CSRF), due to the lack of CSRF protection.

Deeper analysisAI

CVE-2024-54851 is a Cross-Site Request Forgery (CSRF) vulnerability affecting Teedy versions 1.12 and earlier, stemming from the absence of CSRF protection mechanisms. This flaw, classified under CWE-352, carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high severity due to its network accessibility, low complexity, lack of required privileges, and potential for significant impacts on confidentiality, integrity, and availability.

An unauthenticated attacker (PR:N) can exploit this vulnerability by crafting a malicious webpage or resource that, when visited by an authenticated Teedy user (UI:R), triggers unauthorized requests to the Teedy application. Successful exploitation allows the attacker to perform actions on behalf of the victim user, potentially leading to high-impact outcomes such as data modification, deletion, or unauthorized access, depending on the user's privileges within the Teedy instance.
