NewStart CGSL MAIN 6.02 : bash Multiple Vulnerabilities (NS-SA-2021-0118)

high Nessus Plugin ID 154582


The remote NewStart CGSL host is affected by multiple vulnerabilities.


The remote NewStart CGSL host, running version MAIN 6.02, has bash packages installed that are affected by multiple vulnerabilities:

- GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271. (CVE-2014-7169)

- The expansion of '\h' in the prompt string in bash 4.3 allows remote authenticated users to execute arbitrary code via shell metacharacters placed in 'hostname' of a machine. (CVE-2016-0634)

- Bash before 4.4 allows local users to execute arbitrary commands with root privileges via crafted SHELLOPTS and PS4 environment variables. (CVE-2016-7543)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade the vulnerable CGSL bash packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
