| Vulnerability | CVE-2026-25747 |
|---|---|
| Type | Remote Code Execution (RCE) via Deserialization / Input Handling Flaw |
| Description | CVE-2026-25747 is a remote code execution vulnerability caused by improper handling of user-controlled input within the affected application. Based on the provided PoC, the vulnerability allows an attacker to craft a malicious request that triggers unsafe processing logic, leading to execution of arbitrary commands on the target system. The issue stems from insecure parsing or deserialization of attacker-supplied data without proper validation or sanitization. |
| Root Cause | - Lack of input validation on user-supplied data - Unsafe processing (likely deserialization or command injection path) - Trusting external input in backend logic without sanitization |
| Attack Vector | - Remote (network-accessible service) - No authentication required (as demonstrated in PoC) - Exploitable via crafted HTTP request / payload |
| Impact | - Arbitrary command execution on the target system - Full system compromise depending on privileges of the running service - Potential for lateral movement, persistence, and data exfiltration - Can be chained with privilege escalation vulnerabilities |
| Severity | Likely Critical (estimated CVSS ~9.0+) Vector (estimated): AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H |
| Proof of Concept (PoC) | The GitHub repository demonstrates exploitation by: 1. Crafting a malicious payload 2. Sending it to the vulnerable endpoint 3. Triggering execution of arbitrary commands Repository: https://github.com/oscerd/CVE-2026-25747 |
| Technical Details (from PoC) | - Exploit sends specially crafted request to vulnerable endpoint - Payload injects command or serialized object into processing logic - Server executes payload without validation - Response confirms successful execution (command output / reverse shell depending on usage) |
| Detection Methods | - Monitor logs for abnormal request patterns or payloads - Detect suspicious command execution from application processes - Look for outbound connections (reverse shells / callbacks) - Use WAF rules to detect injection/deserialization patterns |
| Indicators of Compromise (IoCs) | - Unexpected process execution spawned by the application - Suspicious HTTP requests with encoded or serialized payloads - Outbound connections to attacker-controlled servers - Presence of web shells or unauthorized files |
| Mitigation | - Implement strict input validation and sanitization - Avoid unsafe deserialization of untrusted data - Apply principle of least privilege for application services - Use WAF/IPS to block malicious payload patterns - Patch the application once vendor fix is available |
| Workarounds | - Restrict access to vulnerable endpoints - Disable unnecessary features handling external input - Block suspicious traffic patterns at network level |
