CVE-2007-5972
HighSummary
Podatność typu double free w funkcji krb5_def_store_mkey w pliku lib/kdb/kdb_default.c w MIT Kerberos 5 (krb5) 1.5 może prowadzić do nieznanego wpływu. Atakujący musi być zdalnie uwierzytelniony i posiadać odpowiednie uprawnienia do przechowywania klucza głównego krb5kdc.
Risk Assessment
Ryzyko dla organizacji polega na możliwości nieautoryzowanego dostępu do klucza głównego, co może prowadzić do poważnych naruszeń bezpieczeństwa. Atakujący z odpowiednimi uprawnieniami może wykorzystać tę podatność do przejęcia kontroli nad systemem.
Recommendation
Zaleca się aktualizację do najnowszej wersji MIT Kerberos, aby usunąć tę podatność. Należy również ograniczyć dostęp do funkcji przechowywania klucza głównego tylko do zaufanych użytkowników.

In cjose versions 0.6.1 through 0.6.2.5, when encrypting a JWE using AES-CBC-HMAC content-encryption algorithms (A128CBC-HS256, A192CBC-HS384, A256CBC-HS512) with any key-management algorithm that generates a fresh content-encryption key (CEK), the CEK is all zero bytes instead of being randomly generated. The resulting JWE is encrypted and authenticated under a fixed, publicly known key, allowing anyone who obtains the JWE to recover plaintext and forge or modify content. Fixed in 0.6.2.6 by generating CEK from RAND_bytes.
- CVE-2026-53581Critical
OPNsense is a FreeBSD based firewall and routing platform. Prior to version 26.1.9 of opnsense/core and version 26.4_20 of BE/opnsense/core, a path traversal vulnerability in the NTP configuration module allows an attacker to overwrite arbitrary files on the system as the root user. By manipulating the GPS or PPS serial port parameter, an attacker with access to the NTP configuration can escape the intended directory and write user-controlled data to any file.
- CVE-2026-85982Critical
The Auth0 AD/LDAP Connector is vulnerable to stored Cross-Site Scripting (XSS) issues due to improper HTML encoding of data in search results and updater log content displayed in the admin panel. An authenticated user with privileges to modify directory attributes, or a low-privileged local user on the host, could insert script content that executes in an administrator's browser.
Original NVD description (English source)
Double free vulnerability in the krb5_def_store_mkey function in lib/kdb/kdb_default.c in MIT Kerberos 5 (krb5) 1.5 has unknown impact and remote authenticated attack vectors. NOTE: the free operations occur in code that stores the krb5kdc master key, and so the attacker must have privileges to store this key.
