Horizon Alert
Summary of the vulnerability and why it matters
This advisory concerns a logic vulnerability in osTicket's password reset function. The flaw allows an attacker who obtains a valid password reset token to bypass expiry checks and potentially reset the password for an affected account, leading to unauthorized access. The primary concern is confirming the relevance and exposure of this issue within your environment.
- Password resets can be exploited.
- Impacts user account access security.
- Confirm if osTicket is used.
Attack Path
How an attacker could exploit the issue
An attacker could gain unauthorized access to a user's account by exploiting a flaw in the password reset process. If an attacker can obtain a valid password reset token, they may be able to bypass the intended expiration check. This could allow them to reset the password and take control of the account.
- No authentication needed for initial access.
- Token bypass allows password reset.
- Account compromise and data theft.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow an attacker to reset a user's password if they can obtain a valid password reset token. This occurs because the system may not properly check if the token has expired when certain conditions are met during the password reset process.
- Account takeover
- Password reset token interception
- Unauthorized account access
Operational Fix
Recommended remediation, mitigation, and detection steps
This vulnerability in osTicket affects the password reset process and could allow an attacker to compromise user accounts. Platform or application owners should first identify all instances of osTicket, determine their exposure to the internet, and confirm business criticality. Subsequently, a remediation plan should be developed based on the assessed risk.
- Platform/Application owners must take ownership.
- Verify osTicket instances and exposure.
- Plan remediation based on risk.
