CVE-2024-8370: Grocy SVG File Upload recipepictures cross site scripting

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.43% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A vulnerability classified as problematic was found in Grocy up to 4.2.0. This vulnerability affects unknown code of the file /api/files/recipepictures/ of the component SVG File Upload Handler. The manipulation of the argument force_serve_as with the input picture' leads to cross site scripting. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted at the moment. Unfortunately, the project maintainer does not want to be quoted in any way regarding the dispute rationale. The security policy of the project implies that this finding is "practically irrelevant" due to authentication requirements.
