Moodle: idor when deleting oauth2 linked accounts
Noroxi assessment
Priority: Monitor (action score 30/100)
- 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: 0.36% (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: github.com/moodle/moodle moodle 4.1.13, 4.2.10, 4.3.7.
Low priority for now. Upgrade to github.com/moodle/moodle moodle 4.1.13, 4.2.10, 4.3.7 or later.
