CVE-2007-6738
CVE-2007-6738 is a security vulnerability in g.rodola pyftpdlib. O3 Security detects and blocks CVE-2007-6738 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.
pyftpdlib before 0.1.1 does not choose a random value for the port associated with the PASV command, which makes it easier for remote attackers to obtain potentially sensitive information…
Description
pyftpdlib before 0.1.1 does not choose a random value for the port associated with the PASV command, which makes it easier for remote attackers to obtain potentially sensitive information about the number of in-progress data connections by reading the response to this command.
Affected Products
pyftpdlibg.rodolaDetection & mitigation playbook
Vendor / applianceDetect
Inventory every g.rodola pyftpdlib 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 exploitation 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-2007-6738 yet — track the g.rodola pyftpdlib 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-2007-6738 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-2007-6738. 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-2007-6738 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2007-6738 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
