Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-072 advisory.

There's a null pointer dereference and server-side request forgery flaw in httpd's mod_proxy module, when it is configured to be used as a forward proxy. A crafted packet could be sent on the adjacent network to the forward proxy that could cause a crash, or potentially SSRF via misdirected Unix Domain Socket requests. In the worst case, this could cause a denial of service or compromise to confidentiality of data. (CVE-2021-44224)

A buffer overflow flaw in httpd's lua module could allow an out-of-bounds write. An attacker who is able to submit a crafted request to an httpd instance that is using the lua module may be able to cause an impact to confidentiality, integrity, and/or availability. (CVE-2021-44790)

A flaw was found in the mod_lua module of httpd. A crafted request body can cause a read to a random memory area due to an uninitialized value in functions called by the parsebody function. The highest treat of this vulnerability is availability. (CVE-2022-22719)

A flaw was found in httpd. The inbound connection is not closed when it fails to discard the request body, which may expose the server to HTTP request smuggling. (CVE-2022-22720)

A flaw was found in httpd, where it incorrectly limits the value of the LimitXMLRequestBody option. This issue can lead to an integer overflow and later causes an out-of-bounds write. (CVE-2022-22721)

An out-of-bounds read/write vulnerability was found in the mod_sed module of httpd. This flaw allows an attacker to overwrite the memory of an httpd instance that is using mod_sed with data provided by the attacker. (CVE-2022-23943)

An HTTP request smuggling vulnerability was found in the mod_proxy_ajp module of httpd. This flaw allows an attacker to smuggle requests to the AJP server, where it forwards requests. (CVE-2022-26377)

An out-of-bounds read vulnerability was found in the mod_isapi module of httpd. The issue occurs when httpd is configured to process requests with the mod_isapi module. (CVE-2022-28330)

An out-of-bounds read vulnerability was found in httpd. A very large input to the ap_rputs and ap_rwrite functions can lead to an integer overflow and result in an out-of-bounds read. (CVE-2022-28614)

An out-of-bounds read vulnerability was found in httpd. A very large input to the ap_strcmp_match function can lead to an integer overflow and result in an out-of-bounds read. (CVE-2022-28615)

A flaw was found in the mod_lua module of httpd. A malicious request to a Lua script that calls parsebody(0) can lead to a denial of service due to no default limit on the possible input size.
(CVE-2022-29404)

A flaw was found in the mod_sed module of httpd. A very large input to the mod_sed module can result in a denial of service due to excessively large memory allocations. (CVE-2022-30522)

A flaw was found in the mod_lua module of httpd. The data returned by the wsread function may point past the end of the storage allocated for the buffer, resulting in information disclosure. (CVE-2022-30556)

A flaw was found in the mod_proxy module of httpd. The server may remove the X-Forwarded-* headers from a request based on the client-side Connection header hop-by-hop mechanism. (CVE-2022-31813)

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.

Solution

Run 'dnf update httpd --releasever=2023.0.20230222 ' to update your system.
