Summary

CVE-2024-53496 is a critical-severity Improper Access Control (CWE-284) vulnerability in Winterchens My-Site. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 31.0th 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 are NIST 800-53 AC-3 (Access Enforcement) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-3 Access Enforcement good match

prevent

Enforces approved authorizations for access to information and system resources, directly preventing unauthenticated attackers from bypassing the flawed doFilter function to reach sensitive components.

SI-2 Flaw Remediation good match

prevent

Requires timely identification, reporting, and correction of the specific access control flaw in my-site v1.0.2.RELEASE to eliminate the vulnerability.

AC-6 Least Privilege partial match

prevent

Employs least privilege to restrict access to only what is necessary, limiting the impact of any successful authentication bypass on sensitive components.

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.

T1087.001 Local Account Discovery

Adversaries may attempt to get a listing of local system accounts.

attack.mitre.org →

Why these techniques?

Vulnerability allows unauthenticated bypass of web authorization filter via URL manipulation (e.g., appending ';'), enabling exploitation of public-facing application (T1190) and access to sensitive endpoints like admin user lists for local account discovery (T1087.001).

NVD Description

Incorrect access control in the doFilter function of my-site v1.0.2.RELEASE allows attackers to access sensitive components without authentication.

Deeper analysisAI

CVE-2024-53496 is an incorrect access control vulnerability in the doFilter function of my-site version 1.0.2.RELEASE. This flaw allows attackers to bypass authentication and access sensitive components. The vulnerability carries a CVSS v3.1 base score of 9.8 (Critical), with vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, and is associated with CWE-284 (Improper Access Control). It was published on 2025-08-22.

Remote attackers require no privileges or user interaction to exploit this over the network with low complexity. Successful exploitation grants high-impact access to sensitive components without authentication, potentially enabling full compromise of confidentiality, integrity, and availability.
