OS Command Injection in D-Link DIR820LA1_FW105B03 (ping_addr parameter)

IdentifiersCVE-2023-25280CWE-78· Improper Neutralization of Special…

CVE-2023-25280 is an OS command injection vulnerability in D-Link DIR820LA1_FW105B03. The vulnerability exists in the ping.ccp component, where the ping_addr parameter is not properly sanitized, allowing attackers to inject arbitrary system commands. Exploitation enables privilege escalation to root, granting full control over the device.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows remote attackers to execute arbitrary commands as root, leading to full device compromise. This can result in persistent malware installation, lateral movement, data exfiltration, and use of the device in botnet campaigns such as RondoDox, which has been observed exploiting this vulnerability in the wild.

Mitigation

If you can’t patch tonight, do this now.

Restrict network access to the device's management interface, especially from untrusted networks. Employ network segmentation to limit exposure. Monitor for abnormal device behavior and unauthorized command execution. Disable unnecessary services and endpoints, and implement web application firewalls or IPS signatures to block known exploit patterns targeting this vulnerability.

Remediation

Patch, then assume compromise.

Apply the latest firmware update from D-Link that addresses CVE-2023-25280. If no patch is available, contact the vendor for mitigation guidance. Remove or restrict access to the ping.ccp endpoint if possible.
