Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Overread Buffers An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

| description | The version of Symantec Endpoint Protection (SEP) Client installed on the remote host is 14.x prior to 14.2.5569.2100. It is, therefore, affected by multiple vulnerabilities: - A privilege escalation vulnerability exists. An unauthenticated, remote attacker can exploit this to compromise the software application to gain elevated access to resources that are normally protected from an application or user. (CVE-2020-5820, CVE-2020-5822, CVE-2020-5823) - A DLL injection vulnerability exists. An unauthenticated, local attacker can exploit this to execute their own code in place of legitimate code as a means to perform an exploit. (CVE-2020-5821) - A denial of service (DoS) vulnerability exists. An unauthenticated, remote attacker can exploit this issue to make the application stop responding.(CVE-2020-5824) - An arbitrary file write vulnerability exists. An unauthenticated, remote attacker can exploit this to overwrite existing files on the resident system without proper privileges. (CVE-2020-5825) - An out-of-bounds read error exists. An unauthenticated, remote attacker can exploit this to read memory outside of the bounds of the memory that had been allocated to the program. (CVE-2020-5826) Note that Nessus has not tested for this issue but has instead relied only on the application |
