Noroxi assessment
Priority: Monitor (action score 33/100)
- 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: 3.7% (FIRST EPSS); higher than 89.9% of all records.
- 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: sdl (Alpine:v3.10) 1.2.15-r12; sdl_image (Alpine:v3.10) 1.2.12-r5; sdl2_image (Alpine:v3.11) 2.0.5-r1.
Low priority for now. Upgrade to sdl (Alpine:v3.10) 1.2.15-r12; sdl_image (Alpine:v3.10) 1.2.12-r5; sdl2_image (Alpine:v3.11) 2.0.5-r1 or later.
