CVE-2025-20364

4.3 MEDIUM

📋 TL;DR

An unauthenticated attacker on the same wireless network can inject fake Device Analytics action frames into Cisco Wireless Access Points. This could corrupt analytics data for legitimate clients connected to the same wireless controller. Only adjacent attackers can exploit this vulnerability.

💻 Affected Systems

Products:
  • Cisco Wireless Access Points
Versions: Specific versions listed in Cisco advisory
Operating Systems: Cisco Wireless AP Software
Default Config Vulnerable: ⚠️ Yes
Notes: Affects APs with Device Analytics feature enabled. Requires attacker to be within wireless range.

⚠️ 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).

  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

Attackers could manipulate Device Analytics data to cause incorrect network decisions, potentially leading to service degradation or misconfigured client handling.

🟠

Likely Case

Data integrity issues in Device Analytics reporting, potentially affecting network monitoring and troubleshooting capabilities.

🟢

If Mitigated

Minimal impact with proper network segmentation and wireless security controls in place.

🌐 Internet-Facing: LOW - Requires physical proximity to wireless network, not remotely exploitable over internet.
🏢 Internal Only: MEDIUM - Requires attacker to be on same wireless network, but could affect internal network monitoring systems.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: MEDIUM

Requires wireless packet crafting knowledge and physical proximity to target network.
