MEDIUMCVSS 5.4/10EPSS 0.36%

Last modified

CVE-2021-3844 is a medium-severity vulnerability rated 5.4/10 on the CVSS scale. Rapid7 InsightVM suffers from insufficient session expiration when an administrator performs a security relevant edit on an existing, logged on user. For example, if a user's password is changed by an administrator due to an otherwise unrelated credential leak, that user account's current session is still valid after the password change, potentially allowing the attacker who originally compromised the credential to remain logged in and able to cause further damage. EPSS estimates a 0.36% chance of exploitation in the next 30 days.
