Description A password aging vulnerability in the RADIUS client of Juniper Networks Junos OS and Junos OS Evolved allows an authenticated, network-based attacker to access the device without enforcing the required password change.
Affected devices allow logins by users for whom the RADIUS server has responded with a reject and required the user to change the password as their password was expired. Therefore the policy mandating the password change is not enforced.
This does not allow users to login with a wrong password, but only with the correct but expired one.
This issue affects:
Junos OS:
* all versions before 22.4R3-S8,
* 23.2 versions before 23.2R2-S4,
* 23.4 versions before 23.4R2-S5,
* 24.2 versions before 24.2R2-S1,
* 24.4 versions before 24.4R1-S3, 24.4R2;
Junos OS Evolved:
* all versions before 22.4R3-S8-EVO,
* 23.2 versions before 23.2R2-S4-EVO,
* 23.4 versions before 23.4R2-S5-EVO,
* 24.2 versions before 24.2R2-S1-EVO,
* 24.4 versions before 24.4R1-S3-EVO, 24.4R2-EVO.
A vulnerability in the RADIUS client of Juniper Networks Junos OS and Junos OS Evolved allows authenticated, network-based attackers to access devices without enforcing mandatory password changes. This issue affects devices that permit logins from users whose passwords have expired, as indicated by a RADIUS server rejection. The vulnerability arises because the policy requiring password updates is not applied, enabling access with correct but expired passwords. This issue impacts multiple versions across both Junos OS and Junos OS Evolved.
