Amazon Linux AMI : golang (ALAS-2023-1760)
critical Nessus Plugin ID 177012

Synopsis
The remote Amazon Linux AMI host is missing a security update.Description
The version of golang installed on the remote host is prior to 1.18.6-1.44. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1760 advisory.html/template: improper sanitization of CSS values
Angle brackets (<>) were not considered dangerous characters when inserted into CSS contexts. Templates containing multiple actions separated by a '/' character could result in unexpectedly closing the CSS context and allowing for injection of unexpected HMTL, if executed with untrusted input. (CVE-2023-24539)
html/template: improper handling of JavaScript whitespace.
Not all valid JavaScript whitespace characters were considered to be whitespace. Templates containing whitespace characters outside of the character set \t\n\f\r\u0020\u2028\u2029 in JavaScript contexts that also contain actions may not be properly sanitized during execution. (CVE-2023-24540)
html/template: improper handling of empty HTML attributes.
Templates containing actions in unquoted HTML attributes (e.g. attr={{.}}) executed with empty input could result in output that would have unexpected results when parsed due to HTML normalization rules.
This may allow injection of arbitrary attributes into tags. (CVE-2023-29400)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
