CVE-2020-7246
HIGHCVE-2020-7246 is a high-severity (CVSS 8.8) Path Traversal vulnerability in qdpm qdpm. 10 public exploit references exist, so weaponization risk is real. O3 Security detects and blocks CVE-2020-7246 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.

Description
A remote code execution (RCE) vulnerability exists in qdPM 9.1 and earlier. An attacker can upload a malicious PHP code file via the profile photo functionality, by leveraging a path traversal vulnerability in the users['photop_preview'] delete photo feature, allowing bypass of .htaccess protection. NOTE: this issue exists because of an incomplete fix for CVE-2015-3884.

Detection & mitigation playbook
Vendor / applianceDetect
Inventory every qdpm qdpm deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Remediation status
No patch has shipped for CVE-2020-7246 yet — track the qdpm qdpm advisory for a fixed release and apply the workarounds below in the meantime.
Mitigate without a patch
Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.
How O3 protects you
O3 detects and blocks CVE-2020-7246 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.
Tailored to CVE-2020-7246. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2020-7246 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2020-7246 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
