Syskey reuses keystream

Overview Versions of SYSKEY in use prior to December, 1999 leave the SAM database vulnerable to cryptanalytic attacks. Description SYSKEY is a utility introduced in Microsoft Windows NT 4.0 service pack 3 to provide strong cryptographic protection to the SAM password database. The protection SYSK...

CVE-2001-1476

SSH before 2.0, with RC4 encryption and the "disallow NULL passwords" option enabled, makes it easier for remote attackers to guess portions of user passwords by replaying user sessions with certain modifications, which trigger different messages depending on whether the guess is correct or not...

CVE-2001-1469

The RC4 stream cipher as used by SSH1 allows remote attackers to modify messages without detection by XORing the original message's cyclic redundancy check CRC with the CRC of a mask consisting of all the bits of the original message that were modified...

CVE-2001-1475

SSH before 2.0, when using RC4 and password authentication, allows remote attackers to replay messages until a new server key VK is generated...

Passwords sent via SSH encrypted with RC4 can be easily cracked

Overview Passwords sent using SSH with RC4 encryption can be easily cracked by an attacker who is able to capture and replay the session. This problem occurs for three reasons: SSH sessions can be replayed, the RC4 encryption algorithm has some specific weaknesses, and the SSH daemon provides too...

SSH connections using RC4 and password authentication can be replayed

Overview This vulnerability may allow an attacker to replay a captured SSH1 session. Description Preconditions: Client requests RC4 and the server grants request Client uses password authentication When an SSH1 session using the RC4 cipher is established, the client and server agree upon a sessio...

Weak CRC allows RC4 encrypted SSH1 packets to be modified without notice

Overview There is an information integrity vulnerability in the SSH1 protocol that allows RC4 encrypted packets to be modified without notice. Description Preconditions: Client has requested RC4 and server supports it. Compression is disabled. When using the RC4 stream cipher, SSH1 uses a cyclic...
