Description

This security bulletin contains information about 4 vulnerabilities.


1) Memory leak (CVE-ID: CVE-2020-5861)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due to the Traffic Management Microkernel (TMM) process may produce a core file in some cases when Ram Cache incorrectly optimizes stored data. A remote attacker can cause a denial of service condition on the target system.


2) Input validation error (CVE-ID: CVE-2020-5857)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to undisclosed HTTP behavior. A remote attacker can cause a denial of service condition on the target system.


3) Command Injection (CVE-ID: CVE-2020-5858)

CWE-ID: CWE-77 - Command injection

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to execute arbitrary commands on the system.

The vulnerability exists due to the improper input validation. A local user with TMOS Shell (tmsh) access can use a specially crafted "tmsh" command and execute arbitrary commands with elevated privileges.


4) Input validation error (CVE-ID: CVE-2020-5859)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send specially crafted HTTP/3 messages, cause the Traffic Management Microkernel (TMM) to produce a core file and perform a denial of service (DoS) attack.
