Overview


Symantec Embedded Security: Critical System Protection (SES:CSP) and Data Center Security: Server Advanced (SDCS:SA) were susceptible to security issues in the management server and deployed agents which could enable unauthorized elevated access, bypassing security protection on agents, potential unauthorized insertion of arbitrary code on agents.

Details


SES:CSP/SDCS:SA Management Server SQL Injection - Management servers were susceptible to potential SQL Injection by an authorized but non-privileged network user. A malicious user with network access to the proper port on the management server could potentially inject arbitrary SQL commands. If successful, the attacker could bypass authentication and potentially get their arbitrary commands to run with the privileges of the application.

SES:CSP/SDCS:SA Management Server Path Traversal - The Management Server did not properly sanitize user-supplied input. An authorized but lower-privileged management server user could potentially execute arbitrary code with elevated privileges.

This is not applicable to 5.2.9 and earlier.

SES:CSP/SDCS:SA Management Server Path Traversal/Binary Planting on Deployed Agent - By leveraging elevated access on the management server, a less-privileged user could potentially deploy specifically-crafted update packages to arbitrary locations on SES:CSP/SDCS:SA deployed agents for possible execution by the agent. This could have resulted in potentially bypassing security protection on agents and resultant arbitrary remote code execution.

This is not applicable to 5.2.9 and earlier.

SES:CSP/SDCS:SA Named Pipe Process Call Arbitrary Argument Injection - An authenticated user who can read/write to a specific named pipe could potentially inject arbitrary arguments which could allow bypass of security protection on the agent.

Symantec is not aware of exploitation of or adverse customer impact from this issue.


Update Information


Updates for SES:CSP 1.0.x and 6.5.0 are available through Symantec File Connect.


Update information for SES:CSP and SDCS:SA is available through TechNote INFO3743, http://www.symantec.com/docs/INFO3743


Symantec Response and Mitigations/Workarounds


Symantec recommends customers upgrade to the latest version. However, if unable to upgrade immediately, there are some workarounds available to mitigate these issues related to SES:CSP/SDCS:SA server and Windows agents.

SES:CSP/SDCS:SA Management Server SQL Injection

Always configure out of the box prevention policy with local network information and apply it to the management server to limit access to local network or just security administrators.

SES:CSP/SDCS:SA Management Server Path Traversal

If a customer has another physical drive available, edit the DCS:SA Server configuration to change the bulk log files directory so the directory resides on a different physical drive than where the DCS:SA Server is installed.

SES:CSP/SDCS:SA Management Server Path Traversal/Binary Planting on Deployed Agent

Symantec recommends upgrading the SES:CSP/SDCS:SA Management Server in order to mitigate this vulnerability on the agent.

Always configure out of the box prevention policy with local network information and apply it to the management server and agent to limit access to local network or just security administrators.

SES:CSP/SDCS:SA Named Pipe Process Call Arbitrary Argument Injection

The latest Symantec Prevention policies contain mitigations for this vulnerability. Symantec recommends that customers upgrade their Prevention policies with the latest policies that are posted on Symantec File Connect.

For Detection-only customers Symantec recommends to stop the Utility Service (SISIPSUtil) on the agent. Note that this will impact event viewer functionality on the agent.

Best Practices


As part of normal best practices, Symantec strongly recommends the following:


  • Restrict access to administrative or management systems to authorized 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 potential exploit.


  • Keep all operating systems and applications current with vendor patches.


  • Follow a multi-layered approach to security. At a minimum, run both firewall and anti-malware applications 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 the detection of attacks or malicious activity related to the exploitation of latent vulnerabilities.
