Security Advisories Relating to Symantec Products - Symantec Intel Alert Management System Multiple Code Execution Issues

SYM11- 002

January 26, 2011

Revision History




CVSS2 Base Score: 7.9
Impact 10.0     Exploitability 5.5

CVSS 2 Base Vector: AV:A/AC:M/Au:N/C:C/I:C/A:C

Exploit Publicly Available: proof of concept


Symantec was notified of multiple instances of failure to properly handle user input in the Third Party Intel Alert Management System(AMS2) which could result in arbitrary code execution.

Affected Product(s)

Product Version Solution
Symantec AntiVirus Corporate Edition Server 10.x Upgrade to SAVCE 10.1 MR10
Symantec System Center 10.x Upgrade to SSC from SAVCE 10.1 MR10
Symantec Quarantine Server 3.6 Upgrade to Quarantine Server from SEP 11.0 MR3 or later
Symantec Quarantine Server 3.5 Upgrade to Quarantine Server from SAVCE 10.1 MR10


The Intel Alert Management System (AMS2) is used in Symantec AntiVirus Corporate Edition Server (SAVCE), Symantec System Center (SSC), and Symantec Quarantine Server. AMS2 listens on TCP Port 38292 and allows SAVCE Administrators to send messages(i.e. email) if a user-specified event occurs.

Symantec was notified of multiple vulnerabilities in AMS2. It is possible to send specially-crafted packets to the targeted server, causing a buffer overflow or allowing arbitrary commands to run, potentially executing arbitrary code. The successful exploitation of these vulnerabilities could result in a possible compromise of the affected products.

AMS2 has not been included in a default install of SAVCE Server or SSC since version 10.0. AMS2 was included in the default install of Quarantine Server prior to SEP 11.0 MR3.

Symantec Response

Symantec engineers verified these issues and released an update to address them. Symantec customers should update to the latest maintenance release available through normal update procedures.

Symantec knows of no exploitation of or adverse customer impact from this issue.


Symantec recommends upgrading any vulnerable versions of SAVCE Server or Symantec System Center to SAVCE 10.1 MR10. Vulnerable versions of Quarantine Server 3.5 should be upgraded to SAVCE 10.1 MR10. Vulnerable versions of Quarantine Server 3.6 should be upgraded to SEP 11.0 MR3 or later. SEP users running a version of Quarantine Server from SEP 11.x later than MR2 are not vulnerable. Reporting has replaced AMS2 as the recommended method of alerting. Symantec recommends that customers who are still using AMS2 switch to Reporting to manage alerts in their environments.

If the customer is unable to switch to Reporting immediately or upgrade to a non-vulnerable version then Symantec recommends that the customer either disable AMS2 as a temporary mitigation or completely uninstall AMS2.

As an additional mitigation, Symantec recommends blocking port 38292 in the corporate environment. This will effectively disable the alert service from sending or receiving messages.

Best Practices

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.
