CVE-2024-32036: SixLabors.ImageSharp vulnerable to data leakage

Noroxi assessment

Priority: Monitor (action score 26/100)

  • 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: 0.57% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: SixLabors.ImageSharp (NuGet) 3.1.4, 2.1.8.

Low priority for now. Upgrade to SixLabors.ImageSharp (NuGet) 3.1.4, 2.1.8 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

ImageSharp is a 2D graphics API. A data leakage flaw was found in ImageSharp's JPEG and TGA decoders. This vulnerability is triggered when an attacker passes a specially crafted JPEG or TGA image file to a software using ImageSharp, potentially disclosing sensitive information from other parts of the software in the resulting image buffer. The problem has been patched in v3.1.4 and v2.1.8.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
