EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Description
system/workplace/views/admin/admin-main.jsp in Alkacon OpenCms before 6.2.2 does not restrict access to administrator functions, which allows remote authenticated users to (1) send broadcast messages to all users (/workplace/broadcast), (2) list all users (/accounts/users), (3) add webusers (/accounts/webusers/new), (4) upload database import and export files (/database/importhttp), (5) upload arbitrary program modules (/modules/modules_import), and (6) read the log file (/workplace/logfileview) by setting the appropriate value for the path parameter in a direct request to admin-main.jsp.
Affected Products
opencmsalkaconDetection & mitigation playbook
Vendor / applianceDetect
Inventory every alkacon opencms 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-2006-3935 yet — track the alkacon opencms 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-2006-3935 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-2006-3935. 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-2006-3935 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2006-3935 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
