NewStart CGSL CORE 5.05 / MAIN 5.05 : httpd Multiple Vulnerabilities (NS-SA-2023-0011)

critical Nessus Plugin ID 174053


The remote NewStart CGSL host is affected by multiple vulnerabilities.


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 HTTP Server versions 2.4.0 to 2.4.46 a specially crafted SessionHeader sent by an origin server could cause a heap overflow (CVE-2021-26691)

- Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP Server 2.4.48 and earlier. (CVE-2021-34798)

- ap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules pass untrusted data to these functions, but third-party / external modules may. This issue affects Apache HTTP Server 2.4.48 and earlier. (CVE-2021-39275)

- A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier. (CVE-2021-40438)

- A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier. (CVE-2021-44790)

- Apache HTTP Server 2.4.52 and earlier fails to close inbound connection when errors are encountered discarding the request body, exposing the server to HTTP Request Smuggling (CVE-2022-22720)

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


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