DescriptionCVE.org

An OS command injection vulnerability was found in yast2-users. When displaying the "Password Settings" tab of a user, get_password_term() in src/include/users/dialogs.rb read the shadowLastChange and shadowExpire fields with GetString(), which performs no numeric validation, and passed the resulting string to format_days_after_epoch(). That helper interpolated the value into a shell command executed via Ruby backticks without quoting or escaping.

Impact: an administrator who manages users against an external/federated LDAP directory via yast2 users triggers root command execution the moment they view or edit that particular user's "Password Settings" tab. No "join domain" or trust setup is required, just browsing/editing one user entry.

This issue affects yast2-users through 5.0.8.

AnalysisAI

OS command injection in yast2-users (through version 5.0.8) allows root-level arbitrary command execution on SUSE Linux systems when an administrator views a malicious LDAP user's Password Settings tab. The get_password_term() function reads shadowLastChange and shadowExpire LDAP attributes without numeric validation and passes them to format_days_after_epoch(), which interpolates the values directly into a shell command executed via Ruby backticks. …

Vulnerability AssessmentAI

Exploitation Exploitation requires all of the following: (1) the target system runs yast2-users version 5.0.8 or earlier on a SUSE Linux distribution; (2) yast2-users is configured to manage users from an external or federated LDAP directory - systems using only local user management are not affected; (3) the attacker has write access sufficient to set arbitrary string values in the `shadowLastChange` or `shadowExpire` LDAP attributes of at least one LDAP user entry; (4) a privileged administrator opens the yast2-users interface and navigates to that specific user's Password Settings tab. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 8.6 (High) with AV:N/AC:L/PR:L/UI:P reflects a meaningful threat when external LDAP integration is active. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade yast2-users to a version beyond 5.0.8 once a patched release is confirmed; no exact fixed version number is available at time of analysis - monitor https://bugzilla.suse.com/show_bug.cgi?id=1272839 for patch availability. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify all SUSE systems running yast2-users version 5.0.8 or earlier and document those with LDAP integration; immediately restrict user management tool access to essential administrators only and review LDAP directory access logs. …
