Noroxi assessment

Priority: Monitor (action score 35/100)

  • 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: 0.29% (FIRST EPSS).
  • 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.
  • Fixed version: YesWiki yeswiki 4.7.0.

Low priority for now. Upgrade to YesWiki yeswiki 4.7.0 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

YesWiki 4.5.0 before 4.7.0 contains an SQL injection vulnerability in PageManager::save(), where the date_maj_fiche field of a Bazar entry-creation request is concatenated unescaped into an INSERT statement. Unauthenticated attackers on default installs can inject a sub-SELECT against wiki_users to exfiltrate password hashes.
