CVE-2023-40260
CriticalCVSS 9.1Exploitation Probability (EPSS)
Low risk40th percentile - higher than 40% of all known CVEs
Summary
EmpowerID versions before 7.205.0.1 allow an attacker to bypass MFA requirements if the first factor (username and password) is known. Knowing the first factor enables changing the account's email address, to which MFA codes are then sent.
Risk Assessment
The organization may be exposed to account takeover, leading to unauthorized access to data and resources. Attackers could use a controlled email address to take over accounts.
Recommendation
It is recommended to update EmpowerID to version 7.205.0.1 or later to mitigate this vulnerability. Additionally, implementing further protective measures, such as monitoring email address changes, is advisable.
Original NVD description (English source)
EmpowerID before 7.205.0.1 allows an attacker to bypass an MFA (multi factor authentication) requirement if the first factor (username and password) is known, because the first factor is sufficient to change an account's email address, and the product would then send MFA codes to the new email address (which may be attacker-controlled). NOTE: this is different from CVE-2023-4177, which claims to be about "some unknown processing of the component Multi-Factor Authentication Code Handler" and thus cannot be correlated with other vulnerability information.
