Title: SEIL/X Series and SEIL/B1 Buffer Overflow and Denial of Service Vulnerabilities

Severity: CRITICAL

Description:

SEIL/X Series and SEIL/B1 are wired/wireless routers.

The devices are prone to the following remote vulnerabilities:

1. A buffer-overflow vulnerability affects the URL-filtering function.

2. A denial-of-service vulnerability affects the NAT function.

Successfully exploiting these issues allows remote attackers to execute arbitrary code with administrative privileges or crash the affected device, denying service to legitimate users.

The following devices are affected:

SEIL/X1 2.40 to 2.51
SEIL/X2 2.40 to 2.51
SEIL/B1 2.40 to 2.51
