CVE-2015-6288
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCisco Content Security Management Appliance (SMA) 7.8.0-000 does not properly validate credentials, which allows remote attackers to cause a denial of service (rapid log-file rollover and application fault) via crafted HTTP requests, aka Bug ID CSCuw09620.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceCisco Content Security Management Appliance (SMA) version 7.8.0-000 contains an improper credential validation vulnerability. Remote attackers can exploit this by sending crafted HTTP requests that trigger rapid log-file rollover, causing application faults and resulting in denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Cisco SMA productIdentify the appliance model by checking the system UI or CLI for 'Content Security Management Appliance' or 'SMA' designationAffected if The device is not a Cisco Content Security Management Appliance
-
Check SMA firmware versionAccess the SMA web interface (or CLI) and locate the firmware version display, typically found under System Administration > Configuration > Version or via 'version' command in CLIAffected if The installed version is 7.8.0-000 (also reported as 7.8_base)
-
Assess HTTP management interface exposureDetermine if the SMA web interface is accessible from external networks or untrusted interfaces by reviewing network ACLs, firewall rules, or interface bindingsAffected if The HTTP/HTTPS management interface is exposed to untrusted networks
-
Inspect logs for rapid log-file rolloverAccess SMA log files (typically via Logs > Configuration or CLI 'logconfig' command) and search for unusually high frequency of log rotation events, large numbers of rollover files, or error messages indicating log subsystem faults occurring in short timeframesAffected if Logs show rapid, excessive log-file rollover activity or log subsystem errors
A user is affected if they are running Cisco SMA version 7.8.0-000 (7.8_base) with the HTTP management interface exposed and logs showing abnormal log-file rollover behavior.
