CVE-2026-38968

ntopng (through 6.6) is reported vulnerable to a Predictable Session Identifier flaw. The issue occurs in HTTPsession creation within src/HTTPserver.cpp, where time-seeded pseudo-randomness can yield deterministic or colliding cookies, enabling session hijacking under attacker-controlled timing. ...

CVE-2026-56016

CGI::Session::ID::md5 versions before 4.49 for Perl generate predictable session ids from low-entropy sources. The generateid method builds the session id from a MD5 digest of the process id, the epoch time, and the built-in rand function. All three are predictable, low-entropy sources: the PID i...

CVE-2026-7830

UltraVNC through 1.8.2.2 uses inadequate cryptography in the MS-Logon II authentication scheme rfbUltraVNCMsLogonIIAuth. In rfb/dh.cpp the Diffie-Hellman key exchange is performed with parameters that fit in an unsigned 64-bit integer DHMAXBITS controls the prime size. A 64-bit DH key can be brok...

CVE-2026-44040

UltraVNC through 1.8.2.2 uses a cryptographically weak pseudo-random number generator to produce VNC authentication challenge bytes. In rfb/vncauth.c:119-129, the vncRandomBytes function seeds libc rand with time0 + getpid + rand and generates a 16-byte challenge. The combined seed space is...
