What is CVE-2026-33771?

CVE-2026-33771 is a critical vulnerability in Juniper Networks CTP OS, published on 9 Apr 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

A Weak Password Requirements vulnerability in the password management function of Juniper Networks CTP OS might allow an unauthenticated, network-based attacker to exploit weak passwords of local accounts and potentially take full control of the device.

The password management menu enables the administrator to set password complexity requirements, but these settings are not saved. The issue can be verified with the menu option "Show password requirements". Failure to enforce the intended requirements can lead to weak passwords being used, which significantly increases the likelihood that an attacker can guess these and subsequently attain unauthorized access.

This issue affects CTP OS versions 9.2R1 and 9.2R2.

Weakness: CWE-521
