Vulnerabilidades

Retrospect and Retrospect Client before 10.0.2.119 on Windows, before 12.0.2.116 on OS X, and before 10.0.2.104 on Linux improperly generate password hashes, which makes it easier for remote attackers to bypass authentication and obtain access to backup files by leveraging a collision.

retroclient.exe in EMC Dantz Retrospect Backup Client 7.5.116 allows remote attackers to cause a denial of service (daemon crash) via malformed packets to TCP port 497, which trigger a NULL pointer dereference.

EMC Dantz Retrospect Backup Client 7.5.116 sends the password hash in cleartext at an unspecified point, which allows remote attackers to obtain sensitive information via a crafted packet.

The Server Authentication Module in EMC Dantz Retrospect Backup Server 7.5.508 uses a "weak hash algorithm," which makes it easier for context-dependent attackers to recover passwords.

retroclient.exe in EMC Dantz Retrospect Backup Client 7.5.116 allows remote attackers to cause a denial of service (daemon crash) via a series of long packets containing 0x00 characters to TCP port 497 that trigger memory corruption, probably involving an English product version on a Chinese OS version.

Buffer overflow in EMC Retrospect Client 5.1 through 7.5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted packet to port 497.

EMC Retrospect for Windows 6.5 before 6.5.382, 7.0 before 7.0.344, and 7.5 before 7.5.1.105 does not drop privileges before opening files, which allows local users to execute arbitrary code via the File>Open dialog.

EMC Retrospect for Windows 6.5 before 6.5.382, 7.0 before 7.0.344, and 7.5 before 7.5.1.105 allows local users to execute arbitrary code by replacing the Retrospect.exe file, possibly due to improper file permissions.

EMC Dantz Retrospect 7 backup client 7.0.107, and other versions before 7.0.109, and 6.5 before 6.5.138 allows remote attackers to cause a denial of service (client termination and loss of backup service) via a malformed packet to TCP port 497, which triggers an assert error.

The installation of Dantz Retrospect Client 5.0.540 on MacOS X 10.2.6, and possibly other versions, creates critical directories and files with world-writable permissions, which allows local users to gain privileges as other users by replacing programs with malicious code.
