CVE-2026-23815

7.2 HIGH

📋 TL;DR

This vulnerability allows authenticated remote attackers with high privileges to perform command injection through a custom binary in AOS-CX Switches' CLI. Successful exploitation could enable execution of unauthorized commands on affected switches. Organizations using vulnerable AOS-CX switches are affected.

💻 Affected Systems

Products:
  • AOS-CX Switches
Versions: Specific versions not provided in reference; check HPE advisory for exact affected versions
Operating Systems: AOS-CX OS
Default Config Vulnerable: ⚠️ Yes
Notes: Requires authenticated remote access with high privileges. Custom binary in CLI is the vulnerable component.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete compromise of the switch allowing attacker to reconfigure network, intercept traffic, pivot to other systems, or disrupt network operations.

🟠

Likely Case

Unauthorized command execution leading to network configuration changes, service disruption, or data interception.

🟢

If Mitigated

Limited impact due to proper access controls, network segmentation, and monitoring preventing successful exploitation.

🌐 Internet-Facing: MEDIUM - Requires authenticated high-privilege access, but internet-facing switches could be targeted if credentials are compromised.
🏢 Internal Only: HIGH - Internal attackers with high privileges could exploit this to gain further network access or disrupt operations.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW - Command injection vulnerabilities typically have low exploitation complexity once access is obtained.

Exploitation requires authenticated high-privilege access. No public exploit code mentioned in advisory.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check HPE advisory for specific patched versions

Vendor Advisory: https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw05027en_us&docLocale=en_US

Restart Required: Yes

Instructions:

1. Review HPE advisory for affected versions. 2. Download appropriate firmware update from HPE support portal. 3. Backup switch configuration. 4. Apply firmware update following HPE documentation. 5. Verify update success and restore configuration if needed.

🔧 Temporary Workarounds

Restrict administrative access

all

Limit administrative access to switches to only necessary personnel and systems using network segmentation and access controls.

Implement command authorization

all

Configure role-based access control to limit which commands users can execute on switches.

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate switches from untrusted networks
  • Enforce strong authentication and limit administrative access to only essential personnel

🔍 How to Verify

Check if Vulnerable:

Check switch firmware version against HPE advisory for affected versions. Review access logs for unauthorized administrative access attempts.

Check Version:

show version (on AOS-CX switch CLI)

Verify Fix Applied:

Verify firmware version has been updated to patched version specified in HPE advisory. Test CLI functionality to ensure no regression.

📡 Detection & Monitoring

Log Indicators:

  • Unusual CLI command execution patterns
  • Multiple failed authentication attempts followed by successful login
  • Commands with unusual parameters or shell metacharacters

Network Indicators:

  • Unexpected network configuration changes
  • Unusual outbound connections from switches
  • Traffic redirection or interception patterns

SIEM Query:

source="switch_logs" AND (event_type="cli_command" AND command="*[;|&`]*") OR (auth_result="success" AND user="admin" AND source_ip="untrusted_network")
