Vulnerability from variot - Updated: 2025-04-10 23:18Cisco Clean Access (CCA) 3.5.x through 3.5.9 and 3.6.x through 3.6.1.1 on the Clean Access Manager (CAM) allows remote attackers to bypass authentication and download arbitrary manual database backups by guessing the snapshot filename using brute force, then making a direct request for the file. Cisco Clean Access (CCA) is prone to a security bypass vulnerability. Cisco Clean Access (CCA) is a software solution for automatically detecting, quarantining, and cleaning devices infected with malicious code from accessing the network.
Secunia is proud to announce the availability of the Secunia Software Inspector.
The Secunia Software Inspector is a free service that detects insecure versions of software that you may have installed in your system. When insecure versions are detected, the Secunia Software Inspector also provides thorough guidelines for updating the software to the latest secure version from the vendor.

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
