Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Validates and sanitizes file uploads in the edit profile function to block crafted HTML or SVG containing XSS payloads.

SI-15 Information Output Filtering good match

prevent

Filters and encodes output when displaying stored profile content to neutralize XSS scripts before execution.

SI-9 Information Input Restrictions partial match

prevent

Restricts allowed file types and formats at upload boundaries to prevent submission of executable HTML or SVG files.

NVD Description

The edit profile function of Grocy through 4.3.0 allows stored XSS and resultant privilege escalation by uploading a crafted HTML or SVG file, a different issue than CVE-2024-8370.

Deeper analysisAI

CVE-2024-55074 is a stored cross-site scripting (XSS) vulnerability, classified under CWE-79, affecting the edit profile function in Grocy through version 4.3.0. It enables attackers to upload crafted HTML or SVG files, which can execute malicious scripts when viewed by other users. This issue is distinct from CVE-2024-8370 and carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact on confidentiality, integrity, and availability.

An authenticated attacker with low privileges can exploit this vulnerability over the network with low complexity and no user interaction required. By uploading a malicious file via the edit profile feature, the attacker triggers stored XSS, which can lead to privilege escalation. This allows the attacker to gain higher-level access within the Grocy application, potentially compromising user data or administrative functions.
