Summary

OneUptime is Vulnerable to Privilege Escalation via Login Response Manipulation

Details

Summary

During the login process, the server response included a parameter called isMasterAdmin. By intercepting and modifying this parameter value from false to true, a user is able to gain access to the admin dashboard interface. However, despite accessing the admin panel, the user does not have sufficient permissions to view or interact with actual data.

PoC

Intercept the login response and change "isMasterAdmin": false → "isMasterAdmin": true

Impact

The admin dashboard is viewable.

Severity ?

6.9 (Medium)

CVE-2025-66028 (GCVE-0-2025-66028)

Vulnerability from cvelistv5 – Published: 2025-11-26 18:11 – Updated: 2025-11-26 18:37

Title

OneUptime is Vulnerable to Privilege Escalation via Login Response Manipulation

Summary

OneUptime is a solution for monitoring and managing online services. Prior to version 8.0.5567, OneUptime is vulnerable to privilege escalation via Login Response Manipulation. During the login process, the server response included a parameter called isMasterAdmin. By intercepting and modifying this parameter value from false to true, it is possible to gain access to the admin dashboard interface. However, an attacker may be unable to view or interact with the data if they still do not have sufficient permissions. This issue has been patched in version 8.0.5567.

Severity ?
