Symantec Endpoint Protection (SEP) and Symantec Endpoint Protection Small Business Edition (SEP SBE), prior to 14.2 RU2 MP1 and prior to 14.2.5569.2100 respectively, may be susceptible to a privilege escalation vulnerability, which is a type of issue whereby an attacker may attempt to compromise the software application to gain elevated access to resources that are normally protected from an application or user.

Symantec Endpoint Protection (SEP) and Symantec Endpoint Protection Small Business Edition (SEP SBE), prior to 14.2 RU2 MP1 and prior to 14.2.5569.2100 respectively, may be susceptible to a DLL injection vulnerability, which is a type of issue whereby an individual attempts to execute their own code in place of legitimate code as a means to perform an exploit.

Symantec Endpoint Protection (SEP) and Symantec Endpoint Protection Small Business Edition (SEP SBE), prior to 14.2 RU2 MP1 and prior to 14.2.5569.2100 respectively, may be susceptible to a privilege escalation vulnerability, which is a type of issue whereby an attacker may attempt to compromise the software application to gain elevated access to resources that are normally protected from an application or user.

A Privilege Escalation vulnerability exists in Symantec Norton Antivirus, Norton AntiVirus with Backup, Norton Security, Norton Security with Backup, Norton Internet Security, Norton 360, Endpoint Protection Small Business Edition Cloud, and Endpoint Protection Cloud Client due to a DLL-preloading without path restrictions, which could let a local malicious user obtain system privileges.

Symantec Endpoint Protection, prior to 14.2 RU2, may be susceptible to a privilege escalation vulnerability, which is a type of issue whereby an attacker may attempt to compromise the software application to gain elevated access to resources that are normally protected from an application or user.

Symantec Endpoint Protection, prior to 14.2 RU2, may be susceptible to an unsigned code execution vulnerability, which may allow an individual to execute code without a resident proper digital signature.

Symantec Endpoint Protection (SEP), prior to 14.2 RU2 & 12.1 RU6 MP10 and Symantec Endpoint Protection Small Business Edition (SEP SBE) prior to 12.1 RU6 MP10d (12.1.7510.7002), may be susceptible to a privilege escalation vulnerability, which is a type of issue whereby an attacker may attempt to compromise the software application to gain elevated access to resources that are normally protected from an application or user.

Symantec Endpoint Protection (SEP), prior to 14.2 RU2 may be susceptible to a password protection bypass vulnerability whereby the secondary layer of password protection could by bypassed for individuals with local administrator rights.

Symantec Endpoint Protection, prior to 14.2 RU1 & 12.1 RU6 MP10 and Symantec Endpoint Protection Small Business Edition, prior to 12.1 RU6 MP10c (12.1.7491.7002), may be susceptible to a privilege escalation vulnerability, which is a type of issue whereby an attacker may attempt to compromise the software application to gain elevated access to resources that are normally protected from an application or user.

Symantec Norton Security prior to 22.16.3, SEP (Windows client) prior to and including 12.1 RU6 MP9, and prior to 14.2 RU1, SEP SBE prior to Cloud Agent 3.00.31.2817, NIS-22.15.2.22, SEP-12.1.7484.7002 and SEP Cloud prior to 22.16.3 may be susceptible to a kernel memory disclosure, which is a type of issue where a specially crafted IRP request can cause the driver to return uninitialized memory.

SEP (Mac client) prior to and including 12.1 RU6 MP9 and prior to 14.2 RU1 may be susceptible to a CSV/DDE injection (also known as formula injection) vulnerability, which is a type of issue whereby an application or website allows untrusted input into CSV files.

Symantec Endpoint Protection prior to 14.2 MP1 may be susceptible to a DLL Preloading vulnerability, which in this case is an issue that can occur when an application being installed unintentionally loads a DLL provided by a potential attacker. Note that this particular type of exploit only manifests at install time; no remediation is required for software that has already been installed. This issue only impacted the Trialware media for Symantec Endpoint Protection, which has since been updated.

Norton prior to 22.15; Symantec Endpoint Protection (SEP) prior to 12.1.7454.7000 & 14.2; Symantec Endpoint Protection Small Business Edition (SEP SBE) prior to NIS-22.15.1.8 & SEP-12.1.7454.7000; and Symantec Endpoint Protection Cloud (SEP Cloud) prior to 22.15.1 may be susceptible to an AV bypass issue, which is a type of exploit that works to circumvent one of the virus detection engines to avoid a specific type of virus protection. One of the antivirus engines depends on a signature pattern from a database to identify malicious files and viruses; the antivirus bypass exploit looks to alter the file being scanned so it is not detected.
