CVE-2018-5238: Symantec Norton Power Eraser

High severity, CVSS 7.8. EPSS: 1.6% chance of exploitation in the next 30 days.

Norton Power Eraser (prior to 5.3.0.24) and SymDiag (prior to 2.1.242) may be susceptible to a DLL Preloading vulnerability, which is a type of issue that can occur when an application looks to call a DLL for execution and an attacker provides a malicious DLL to use instead. Depending on how the application is configured, it will generally follow a specific search path to locate the DLL. The vulnerability can be exploited by a simple file write (or potentially an over-write) which results in a foreign DLL running under the context of the application.

Affected products

• Symantec Norton Power Eraser: before 5.3.0.24 (fixed in 5.3.0.24)
• Symantec Symdiag: before 2.1.242 (fixed in 2.1.242)
