CVE-2026-48691

FastNetMon Community Edition through 1.2.9 contains an integer overflow in the BGP ASPATH attribute encoder. In src/bgpprotocol.hpp, the IPv4UnicastAnnounce::getattributes function computes attributelength as 'sizeofbgpaspathsegmentelementt + this-aspathasns.size sizeofuint32t' and stores it in a...

CVE-2026-48693

FastNetMon Community Edition through 1.2.9 is vulnerable to a local symlink attack via predictable file paths in /tmp. The statistics file path defaults to '/tmp/fastnetmon.dat' src/fastnetmon.cpp line 159. The printscreencontentsintofile function src/fastnetmonlogic.cpp line 2186 opens this path...

DEBIAN-CVE-2026-48697

FastNetMon Community Edition through 1.2.9 does not verify TLS certificates on outbound HTTPS connections. The executewebrequestsecure function in src/fastlibrary.cpp creates a boost::asio::ssl::context with tlsclient mode and calls setdefaultverifypaths to load CA certificates, but never calls...
