- 漏洞信息

688
OpenSSH UseLogin Environment Variable Local Command Execution
Local Access Required Input Manipulation, Misconfiguration
Loss of Confidentiality, Loss of Integrity, Loss of Availability Upgrade
Exploit Public Vendor Verified

- 漏洞描述

OpenSSH contains a flaw that may allow a malicious local attacker to execute arbitrary code on the system. The issue is triggered by a vulnerability in the UseLogin configuration option. If the UseLogin option is enabled, a local attacker can set the LD_PRELOAD or LD_LIBRARY_PATH environment variable to point to a maliciously created shared library file, which would be executed with superuser privileges when the login program is executed. This flaw may lead to a loss of Confidentiality, Integrity, and/or Availability.

Upgrade to version 3.0.2 or higher, as it has been reported to fix this vulnerability. It is also possible to correct the flaw by applying the vendor-supplied patch, or by disabling UseLogin in the configuration.
