CVE-2023-36049: .NET, .NET Framework, and Visual Studio Elevation of Privilege Vulnerability
Noroxi assessment
Priority: Plan (action score 41/100)
- 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: 6.7% (FIRST EPSS); higher than 93.9% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: aspnetcore-runtime-6.0 (AlmaLinux:8) 6.0.25-1.el8_9; aspnetcore-runtime-7.0 (AlmaLinux:8) 7.0.14-1.el8_9; aspnetcore-runtime-8.0 (AlmaLinux:8) 8.0.0-2.el8_9.
- Severity is disputed: the assigning authority (CNA) scores it 7.6, NVD 9.8.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Add it to your regular patch cycle. Upgrade to aspnetcore-runtime-6.0 (AlmaLinux:8) 6.0.25-1.el8_9; aspnetcore-runtime-7.0 (AlmaLinux:8) 7.0.14-1.el8_9; aspnetcore-runtime-8.0 (AlmaLinux:8) 8.0.0-2.el8_9 or later.

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.
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.
