CVE-2025-1532
📋 TL;DR
The Phoneservice module contains a code injection vulnerability (CWE-94) that allows attackers to execute arbitrary code by injecting malicious input. Successful exploitation could compromise service confidentiality and integrity. This affects systems running vulnerable versions of the Phoneservice module.
💻 Affected Systems
- Phoneservice module
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing remote code execution, data theft, and complete service disruption.
Likely Case
Unauthorized access to sensitive phone service data, service manipulation, and potential privilege escalation.
If Mitigated
Limited impact with proper input validation and network segmentation in place.
🎯 Exploit Status
Code injection vulnerabilities typically require crafting specific malicious input but can be exploited without authentication if the vulnerable endpoint is exposed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions
Vendor Advisory: https://www.honor.com/global/security/cve-2025-1532/
Restart Required: Yes
Instructions:
