TITLE
Multiple 3com H3C Device SSH Service Program Denial of Service Vulnerability
Trust: 0.6
DESCRIPTION
Multiple 3Com H3C switches have security issues, and remote attackers can exploit vulnerabilities to perform denial of service attacks on their SSH servers. An unspecified error exists in the built-in SSH server. The attacker sends a specially constructed SSH message to restart the device. Multiple 3Com H3C devices are prone to a remote denial-of-service vulnerability. Successfully exploiting this issue allows remote attackers to cause the affected device to restart, denying service to legitimate users. This issue affects the H3C S3100, Switch 4500, and Switch 4200G series of products. ---------------------------------------------------------------------- Looking for a job? Secunia is hiring skilled researchers and talented developers. The vulnerability is caused due to an unspecified error and can be exploited to cause an affected device to reboot by sending specially crafted SSH packets to it. Successful exploitation requires that the device is configured as SSH server. SOLUTION: Update to the latest versions. H3C S3100-52P: Update to Comware 3.10 Release 1702P13. 3Com Switch 4500: Update to version 3.03.02p09 3Com Switch 4200: Update to version 3.2.4. PROVIDED AND/OR DISCOVERED BY: Reported by the vendor.
