CVE-2015-10123
📋 TL;DR
This vulnerability allows an unauthenticated attacker to craft malicious packets that trigger a buffer overflow when an authenticated user views them in the web management interface. Successful exploitation grants full device control. Affected devices are those running vulnerable firmware versions with web management enabled.
💻 Affected Systems
- Specific device models not publicly listed in available references
⚠️ 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).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise allowing attacker to execute arbitrary code, steal credentials, pivot to internal networks, and maintain persistent access.
Likely Case
Attacker gains administrative privileges on the device, enabling configuration changes, data exfiltration, and use as a foothold for further attacks.
If Mitigated
With proper network segmentation and access controls, impact is limited to the affected device only.
🎯 Exploit Status
Requires two-step exploitation: attacker sends crafted packets, then authenticated user must view them in specific web page.
🛠️ Fix & Mitigation
