Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 31.6th 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 SI-10 (Information Input Validation) and SI-15 (Information Output Filtering).
Deeper analysis
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.
