Security Bulletin
This security bulletin contains one low risk vulnerability.
1) Privilege escalation
EUVDB-ID: #VU9526
Risk: Low
CVSSv3.1: 8.1 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:U/RC:C]
CVE-ID: N/A
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to boundary error in a kernel driver, PGPwded.sys, in Symantec Encryption Desktop when processing input/output control requests (IOCTLs). A local attacker can send specially crafted input/output control requests (IOCTLs), trigger memory corruption, attain arbitrary hard disk read and write access at sector level, subsequently infect the target, gain low level persistence (MBR/VBR) and execute arbitrary code in the context of the built-in SYSTEM user account, without requiring a reboot.
Successful exploitation of the vulnerability may result in system compromise.
Cybersecurity Help is currently unaware of any solutions addressing the vulnerability.
Symantec Encryption Desktop: 10.2.0 - 10.4.2
Symantec Endpoint Encryption: 11.0.0 - 11.1.3
