CVE-2026-48695: FastNetMon Community Edition

CVE-2026-48685

CVE-2026-48685 affects FastNetMon Community Edition up to 1.2.9. The issue is an out-of-bounds memory access caused by incorrect handling of BGP path attributes when the extended length flag is set. In parse_raw_bgp_attribute(), extended_length_bit triggers a 2-byte length field, but the code rea...

CVE-2026-48694

CVE-2026-48694 affects FastNetMon Community Edition up to 1.2.9 via the Juniper router integration plugin. The vulnerability arises because the variable $IP_ATTACK (from argv[1]) is directly interpolated into NETCONF set-configuration commands without validation, allowing an attacker-controlled I...

CVE-2026-48693

CVE-2026-48693 concerns the FastNetMon Community Edition up to 1.2.9. The issue is a local symlink attack due to predictable file paths in /tmp, notably the default statistics file at '/tmp/fastnetmon.dat'. The vulnerable code path opens this path with std::ios::trunc without following symlinks o...

CVE-2026-48687

CVE-2026-48687 affects FastNetMon Community Edition up to 1.2.9, specifically the Juniper router integration plugin. The OS command injection stems from the PHP file src/juniper_plugin/fastnetmon_juniper.php (log function) which builds shell commands by concatenating unsanitized user data from ar...

EUVD-2026-31956

FastNetMon Community Edition through 1.2.9 contains an off-by-one heap-based buffer overflow in the dynamicbinarybuffert class src/dynamicbinarybuffer.hpp. Five methods appenddynamicbuffer, appenddataaspointer, appenddataasobjectptr, memcpyfromptr, memcpyfromobjectptr use an incorrect bounds chec...

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...
