Insecure default directory and file permissions may allow local users to gain escalated privileges.
Due to insecure default directory and file permissions, it is possible for local, non-privileged users to potentially replace key Symantec Discovery components with malicious content.
On July 23, 2007 security firm Secunia issued a security advisory relating to insecure file permissions on Symantec Discovery. This advisory relates to the default file permissions set at installation on the Symantec Discovery server.
The Symantec Discovery product was designed by its 3rd-Party vendor, Centennial Software, such that anyone with access to the Discovery server should have the ability to run the Discovery Control Center. Symantec recommends that server access be restricted to administrators only. For most customers, administrative access only is allowed to the Discovery server. These customers are not affected by this issue. For customers who would like to implement a higher level of security than what is already present within their implementation, we recommend more stringent file based permissions on the directory be set to limit access from unauthorized local users. Please contact your Symantec Support representative for any required assistance.
As part of normal best practices, Symantec strongly recommends:
- Restrict access to administration or management systems to privileged users.
- Restrict remote access, if required, to trusted/authorized systems only.
- Run under the principle of least privilege where possible to limit the impact of exploit by threats.
- Keep all operating systems and applications updated with the latest vendor patches.
- Follow a multi-layered approach to security. Run both firewall and anti-malware applications, at a minimum, to provide multiple points of detection and protection to both inbound and outbound threats.
- Deploy network and host-based intrusion detection systems to monitor network traffic for signs of anomalous or suspicious activity. This may aid in detection of attacks or malicious activity related to exploitation of latent vulnerabilities
