The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has httpd packages installed that are affected by multiple vulnerabilities:
-
In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match ‘$’ to a newline character in a malicious filename, rather than matching only the end of the filename. This could be exploited in environments where uploads of some files are are externally blocked, but only by matching the trailing portion of the filename. (CVE-2017-15715)
-
In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a Session header. This comes from the HTTP_SESSION variable name used by mod_session to forward its data to CGIs, since the prefix HTTP_ is also used by the Apache HTTP Server to pass HTTP header fields, per CGI specifications. (CVE-2018-1283)
-
A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30 due to an out of bound read while preparing data to be cached in shared memory. It could be used as a Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.
(CVE-2018-1303) -
In Apache HTTP server 2.4.0 to 2.4.39, Redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an unexpected URL within the request URL. (CVE-2019-10098)
-
In Apache HTTP Server 2.4.0 to 2.4.41, redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within the request URL. (CVE-2020-1927)
-
In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp may use uninitialized memory when proxying to a malicious FTP server. (CVE-2020-1934)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
