|
Description: |
Symantec Endpoint Protection Windows Agent, running an ERASER Engine prior to 119.1.7.8, may be susceptible to an Elevation of Privilege vulnerability, which may allow an attacker to delete resources that are normally protected from an application or user. |
Mitigation & Additional Information
Symantec Endpoint Protection Windows Agent Virus and Spyware Protection definitions have been made available which addresses this issue. No action is required if LiveUpdate for this content is enabled. If not, run LiveUpdate to update to ERASER Engine 119.1.7.8 by applying Virus and Spyware Protection definitions dated April 2nd, 2025 or greater.
Broadom's Enteprrise Security Group recommends the following measures to reduce risk of attack:
- Restrict access to administrative or management systems to authorized privileged users.
- Restrict remote access 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 for 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.
