CVE-2024-45623

9.8 CRITICAL

📋 TL;DR

This critical vulnerability allows remote attackers to execute arbitrary code on D-Link DAP-2310 access points via a stack-based buffer overflow in the HTTP server. Attackers can exploit this without authentication by sending specially crafted PHP HTTP GET requests. Only organizations using these unsupported devices are affected.

💻 Affected Systems

Products:
  • D-Link DAP-2310
Versions: Firmware 1.16RC028
Operating Systems: Embedded Linux
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects products no longer supported by D-Link. Requires HTTP service to be enabled and accessible.

⚠️ 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 device compromise leading to persistent backdoor installation, network pivoting to internal systems, and data exfiltration.

🟠

Likely Case

Remote code execution allowing attackers to modify device configuration, intercept network traffic, or use the device as a foothold for further attacks.

🟢

If Mitigated

Limited impact if device is isolated in a restricted network segment with strict firewall rules.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Buffer overflow in PHP request handling makes exploitation straightforward for skilled attackers.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: None available

Vendor Advisory: https://supportannouncement.us.dlink.com/security/publication.aspx?name=SAP10406

Restart Required: No

Instructions:

No official patch exists. Device is end-of-life and unsupported.

🔧 Temporary Workarounds

Disable HTTP Management

all

Disable the HTTP management interface and use alternative management methods

Access device CLI and disable HTTP service

Network Segmentation

all

Isolate affected devices in restricted network segments

Configure firewall rules to restrict access to device management interfaces

🧯 If You Can't Patch

  • Immediately replace affected devices with supported hardware
  • Implement strict network access controls to limit exposure

🔍 How to Verify

Check if Vulnerable:

Check device firmware version via web interface or CLI. If version is 1.16RC028, device is vulnerable.

Check Version:

Check web interface or use CLI command specific to D-Link devices

Verify Fix Applied:

No fix available to verify. Only mitigation is device replacement.

📡 Detection & Monitoring

Log Indicators:

  • Unusual HTTP requests to PHP endpoints
  • Multiple failed buffer overflow attempts
  • Unexpected process crashes in httpd

Network Indicators:

  • Malformed HTTP GET requests targeting PHP files
  • Traffic patterns suggesting exploit attempts

SIEM Query:

http.method:GET AND http.uri:*php* AND device.vendor:D-Link AND device.model:DAP-2310
