==================================================================== CERT-Renater Note d'Information No. 2012/VULN478 ____________________________________________________________________ DATE : 12/12/2012 HARDWARE PLATFORM(S): / OPERATING SYSTEM(S) : Systems running Symantec Endpoint Protection Manager, Symantec Protection Center. ====================================================================== http://www.symantec.com/security_response/securityupdates/detail.jsp?fid=security_advisory&pvid=security_advisory&year=&suid=20121210_00 ______________________________________________________________________ Security Advisories Relating to Symantec Products - Symantec Endpoint Protection Management Consoles Multiple Issues SYM12-019 December 10, 2012 Revisions None Severity CVSS2 Impact Exploitability CVSS2 Vector Base Score SEPM/SPC PHP Script Insufficient Validation Remote Code Execution - High 9.3 10 8.6 AV:N/AC:M/AU:N/C:C/I:C/A:C SNAC Unquoted search path local code execution - Medium 4.6 6.44 3.94 AV:L/AC:L/Au:N/C:P/I:P/A:P Overview The management console in Symantec Endpoint Protection Manager (SEPM) and Symantec Protection Center (SPC) for SEP 12.0 Small Business Edition, contains PHP scripts that do not provide proper validation to external input. This could potentially result in remote code execution. Symantec Network Access Control (SNAC) contains an unquoted search path that could potentially permit local code execution and possible elevation of privilege. Affected Products SEPM PHP Script Insufficient Validation Remote Code Execution - High Product Version Build Solution(s) Symantec Endpoint 11.0 All Upgrade to SEP 11.0 Protection(Management RU7-MP3 or the latest Console) release of SEP 12.1 RU2 Symantec Endpoint 12.0 All Upgrade to SEP 12.1 RU2 Protection Small Business Edition (Management Console) Symantec Endpoint 12.1 All Upgrade to SEP 12.1 RU2 Protection(Management Console) SNAC Unquoted path potential arbitrary execution Symantec Network Access 12.1 All Upgrade to SEP 12.1 RU2 Control Products Not Affected Product Version Symantec Network Access Control 11.0 Details Symantec was notified of vulnerabilities in the PHP scripts in the Symantec Endpoint Protection Manager (Symantec Protection Center for SEP 12.0 Small Business Edition). Insufficient validation is done on external input to these scripts. This could allow an unauthorized user who is able to access the console to potentially execute arbitrary code with application privileges. Symantec Network Access Control, shipped as an optional add-on to Symantec Endpoint Protection, contains an unquoted search path that could allow a local user to execute arbitrary code. The local user would need to be able to place their executable in the root path to be executed during application startup. In a recommended installation, the Symantec Endpoint Protection Manager, or Symantec Protection Center, should be hosted behind the corporate firewall with restricted external access. Normal access to the system hosting SEPM or SPC should be restricted to privileged users as a security best practice. If it is necessary to deploy SEPM or SPC outside the corporate network, Symantec strongly recommends configuring client/server communication only and blocking all access to the management console. Symantec Response Symantec product engineers verified the reported issues and resolved these issues in the Symantec Endpoint Protection or Symantec Network Access Control releases identified above. Update Information Updates are available through customers normal support/download locations. 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 Credit Symantec credits an anonymous contributor working with Beyond Security's SecuriTeam Secure Disclosure program for reporting the php script issues in Symantec Endpoint Protection Manager.
