CVE-2007-6043
HighSummary
Funkcja CryptGenRandom w systemie Microsoft Windows 2000 generuje przewidywalne wartości, co ułatwia atakującym uzyskanie dostępu do mechanizmów kryptograficznych. Problem ten dotyczy bezpieczeństwa wstecznego i bezpieczeństwa w przyszłości, związanych z użyciem ośmiu instancji szyfru RC4.
Risk Assessment
Przewidywalność wartości generowanych przez CryptGenRandom może prowadzić do osłabienia mechanizmów kryptograficznych, co stwarza ryzyko dla poufności i integralności danych w organizacji.
Recommendation
Zaleca się aktualizację systemu do nowszej wersji, która nie zawiera tej podatności oraz wdrożenie silniejszych mechanizmów kryptograficznych.

- CVE-2026-53939Critical
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)
The CryptGenRandom function in Microsoft Windows 2000 generates predictable values, which makes it easier for context-dependent attackers to reduce the effectiveness of cryptographic mechanisms, as demonstrated by attacks on (1) forward security and (2) backward security, related to use of eight instances of the RC4 cipher, and possibly a related issue to CVE-2007-3898.
