Horizon Alert
Summary of the vulnerability and why it matters
This advisory concerns an unauthenticated PHP Object Injection vulnerability found in Stargaze versions up to 1.10. This type of vulnerability can allow unauthorized attackers to execute arbitrary code by manipulating how the application handles serialized data. The primary concern is to confirm if this specific technology is in use and assess potential exposure.
- Allows unauthenticated code execution.
- Critical flaw, widely exploitable if used.
- Confirm relevance and assess potential exposure.
Attack Path
How an attacker could exploit the issue
An unauthenticated attacker can exploit this vulnerability by sending a specially crafted request to a vulnerable Stargaze installation. This request targets the PHP Object Injection flaw, allowing the attacker to inject malicious PHP objects. If successful, this could lead to the execution of arbitrary code on the server.
- No authentication required.
- Triggered by sending a crafted request.
- Potential for arbitrary code execution.
Live Threat
Current exploitation, exposure, and threat context
Unauthenticated PHP Object Injection in Stargaze could allow an attacker to execute arbitrary code on the server. This is possible when the affected software processes unsanitized user input that can be deserialized, potentially leading to a compromise of the entire system.
- Server-side code execution.
- Unauthenticated remote code injection.
- Complete system compromise.
Operational Fix
Recommended remediation, mitigation, and detection steps
This unauthenticated PHP Object Injection vulnerability in Stargaze affects internet-facing web applications. The first practical step is for the web application or platform team to identify all Stargaze installations, determine their reachability and business criticality, and locate the accountable owner. Remediation planning should then be prioritized based on this risk assessment.
- Application owners should manage remediation.
- Verify all Stargaze installations.
- Plan remediation based on risk.
