CVE-2025-15348
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on Anritsu ShockLine systems by tricking users into opening malicious CHX files. Attackers can gain control of affected systems through deserialization flaws in CHX file parsing. Organizations using Anritsu ShockLine products are affected.
💻 Affected Systems
- Anritsu ShockLine
📦 What is this software?
Shockline by Anritsu
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control over the ShockLine device, potentially pivoting to other network systems.
Likely Case
Local privilege escalation or limited code execution within the ShockLine application context, potentially disrupting testing operations.
If Mitigated
No impact if proper file validation and user awareness controls prevent malicious CHX files from being processed.
🎯 Exploit Status
Requires user interaction but exploit complexity is low once malicious file is opened
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown - check vendor advisory
Vendor Advisory: Not provided in references
Restart Required: Yes
Instructions:
1. Contact Anritsu for patch availability 2. Apply vendor-provided update 3. Restart affected systems
🔧 Temporary Workarounds
Restrict CHX file handling
allBlock or restrict processing of CHX files from untrusted sources
User awareness training
allTrain users not to open CHX files from unknown or untrusted sources
🧯 If You Can't Patch
- Implement application whitelisting to prevent unauthorized code execution
- Use network segmentation to isolate ShockLine systems from critical infrastructure
🔍 How to Verify
Check if Vulnerable:
Check ShockLine version against vendor advisory when availableCheck Version:
Check within ShockLine application interface or contact vendorVerify Fix Applied:
Verify installed version matches or exceeds patched version from vendor📡 Detection & Monitoring
Log Indicators:
- Unexpected process execution from ShockLine
- CHX file parsing errors
- Unusual network connections from ShockLine system
Network Indicators:
- Outbound connections from ShockLine to unexpected destinations
- File transfers to/from ShockLine system
SIEM Query:
Process creation where parent process contains 'ShockLine' AND command line contains suspicious patterns
