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: 5.6% (FIRST EPSS); higher than 92.8% 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.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- According to the record, no fixed version is available yet.
- Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.

A vulnerability in multiple Atlassian products allows a remote, unauthenticated attacker to bypass Servlet Filters used by first and third party apps. The impact depends on which filters are used by each app, and how the filters are used. This vulnerability can result in authentication bypass and cross-site scripting. Atlassian has released updates that fix the root cause of this vulnerability, but has not exhaustively enumerated all potential consequences of this vulnerability. Atlassian Bamboo versions are affected before 8.0.9, from 8.1.0 before 8.1.8, and from 8.2.0 before 8.2.4. Atlassian Bitbucket versions are affected before 7.6.16, from 7.7.0 before 7.17.8, from 7.18.0 before 7.19.5, from 7.20.0 before 7.20.2, from 7.21.0 before 7.21.2, and versions 8.0.0 and 8.1.0.
