Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability exists in Omnispace Agora Project that could allow unauthorized access by bypassing authentication. This occurs when an attacker uses a stolen password hash to impersonate legitimate users, including administrators, by manipulating specific cookies.
- Stolen password hashes grant unauthorized access.
- Critical access risk to sensitive applications.
- Confirm relevance and potential exposure.
Attack Path
How an attacker could exploit the issue
Attackers can bypass authentication by obtaining a user's bcrypt password hash. By treating this hash as a directly replayable credential in specific cookies, an attacker can impersonate any user, including administrators, to gain unauthorized access to the application.
- Requires a stolen password hash.
- Exploits cookie-based authentication.
- Leads to unauthorized administrative access.
Live Threat
Current exploitation, exposure, and threat context
When supported by the advisory, attackers possessing a user's stored bcrypt password hash could bypass authentication to impersonate any user, including administrators, and gain unauthorized access to the application.
- User account access at risk.
- Stolen password hashes could be replayed.
- Unauthorized application access is possible.
Operational Fix
Recommended remediation, mitigation, and detection steps
The Omnispace Agora Project's authentication bypass vulnerability likely falls under the responsibility of application owners and platform teams. The first practical step is to inventory all instances of the affected technology, confirm their internet reachability and business criticality, and identify the specific application owner responsible for each. Once identified, remediation can be planned based on the assessed risk.
- Application and platform teams own resolution.
- Verify internet-facing instances and criticality.
- Plan remediation with vendor coordination.
