NewStart CGSL CORE 5.04 / MAIN 5.04 : ruby Multiple Vulnerabilities (NS-SA-2019-0080)
Medium Nessus Plugin ID 127292
Synopsis
The remote machine is affected by multiple vulnerabilities.
Description
The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has ruby packages installed that are affected by multiple vulnerabilities:
- An issue was discovered in RubyGems 2.6 and later through 3.0.2. The gem owner command outputs the contents of the API response directly to stdout.
Therefore, if the response is crafted, escape sequence injection may occur. (CVE-2019-8322)
- An issue was discovered in RubyGems 2.6 and later through 3.0.2. Gem::GemcutterUtilities#with_response may output the API response to stdout as it is. Therefore, if the API side modifies the response, escape sequence injection may occur. (CVE-2019-8323)
- An issue was discovered in RubyGems 2.6 and later through 3.0.2. A crafted gem with a multi-line name is not handled correctly. Therefore, an attacker could inject arbitrary code to the stub line of gemspec, which is eval-ed by code in ensure_loadable_spec during the preinstall check. (CVE-2019-8324)
- An issue was discovered in RubyGems 2.6 and later through 3.0.2. Since Gem::CommandManager#run calls alert_error without escaping, escape sequence injection is possible. (There are many ways to cause an error.) (CVE-2019-8325)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Upgrade the vulnerable CGSL ruby packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
