Noroxi assessment

Priority: Monitor (action score 22/100)

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: 0.63% (FIRST EPSS); higher than 50.2% of all records.
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. Special conditions such as timing or configuration are required.
Fixed version: GitHub GitHub Enterprise Server 3.11.16, 3.12.10, 3.13.5.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to GitHub GitHub Enterprise Server 3.11.16, 3.12.10, 3.13.5 or later.

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

An information disclosure vulnerability was identified in GitHub Enterprise Server via attacker uploaded asset URL allowing the attacker to retrieve metadata information of a user who clicks on the URL and further exploit it to create a convincing phishing page. This required the attacker to upload malicious SVG files and phish a victim user to click on that uploaded asset URL. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.14 and was fixed in versions 3.14.2, 3.13.5, 3.12.10, 3.11.16. This vulnerability was reported via the GitHub Bug Bounty program.
