Fuji Electric V-Server is prone to multiple unspecified heap-based buffer overflow vulnerabilities. Successfully exploiting this issue allows attackers to execute arbitrary code in the context of the affected application. Failed exploits will result in denial-of-service conditions. V-Server 184.108.40.206 and prior are vulnerable.
- Fuji Electric V-Server 220.127.116.11
- Fuji Electric V-Server 18.104.22.168
- Fuji Electric V-Server 22.214.171.124
- Fuji Electric V-Server 126.96.36.199
- Fuji Electric V-Server 188.8.131.52
- Fuji Electric V-Server 184.108.40.206
Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.
Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to detect and block attacks and anomalous activity such as requests containing suspicious URI sequences. Since the webserver may log such requests, review its logs regularly.
Implement multiple redundant layers of security.
Various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attacker's ability to exploit this vulnerability to execute arbitrary code.
Updates are available. Please see the references or vendor advisory for more information.
