CVE-2014-3913
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 · uneditedStack-based buffer overflow in AccessServer32.exe in Ericom AccessNow Server allows remote attackers to execute arbitrary code via a request for a non-existent file.
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 confidenceA stack-based buffer overflow vulnerability exists in AccessServer32.exe in Ericom AccessNow Server. The vulnerability is triggered when the server processes a request for a non-existent file, which causes a buffer overflow on the stack, allowing remote attackers to execute arbitrary code.
