Noroxi assessment
Priority: Monitor (action score 23/100)
- Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 11.2% (FIRST EPSS); higher than 95.9% of all records.
- No special conditions are required; it is repeatable.
- Fixed version: quagga (Debian:10) 0.99.3-2; quagga (Debian:3.1) 0.98.3-7.2; quagga (openSUSE:Tumbleweed) 1.2.4-2.14.
Low priority for now. Upgrade to quagga (Debian:10) 0.99.3-2; quagga (Debian:3.1) 0.98.3-7.2; quagga (openSUSE:Tumbleweed) 1.2.4-2.14 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
RIPd in Quagga 0.98 and 0.99 before 20060503 does not properly implement configurations that (1) disable RIPv1 or (2) require plaintext or MD5 authentication, which allows remote attackers to obtain sensitive information (routing state) via REQUEST packets such as SEND UPDATE.
