Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Improper Authentication (CVE-ID: CVE-2022-31813)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error in mod_proxy implementation, where the web server may not send the X-Forwarded-* headers to the origin server based on client side Connection header hop-by-hop mechanism. A remote attacker can bypass IP based authentication on the origin server/application and gain access to otherwise restricted functionality.
2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-36760)
The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests in mod_proxy_ajp. A remote attacker can send a specially crafted HTTP request to the web server and smuggle arbitrary HTTP headers to the AJP server it forwards requests to.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
3) Resource exhaustion (CVE-ID: CVE-2022-30522)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to mod_sed does not properly control consumption of internal resources, if the web server is configured to do transformations with mod_sed in contexts where the input to mod_sed may be very large. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
4) Use-after-free (CVE-ID: CVE-2022-43680)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error caused by overeager destruction of a shared DTD in XML_ExternalEntityParserCreate. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.
5) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2022-4304)
The vulnerability allows a remote attacker to obtain sensitive information.
The vulnerability exists due to a timing based side channel exists in the OpenSSL RSA Decryption implementation. A remote attacker can perform a Bleichenbacher style attack and decrypt data sent over the network.
To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE.
6) Use-after-free (CVE-ID: CVE-2023-0215)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the BIO_new_NDEF function. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.
7) Type Confusion (CVE-ID: CVE-2023-0286)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion error related to X.400 address processing inside an X.509 GeneralName. A remote attacker can pass specially crafted data to the application, trigger a type confusion error and perform a denial of service (DoS) attack or read memory contents.
In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network.
8) HTTP response splitting (CVE-ID: CVE-2022-37436)
The vulnerability allows a remote attacker to perform HTTP splitting attacks.
The vulnerability exists due to software does not correctly process CRLF character sequences within the mod_proxy module. A remote attacker can send specially crafted request containing CRLF sequence and make the application to send a split HTTP response.
Successful exploitation of the vulnerability may allow an attacker perform cache poisoning attack.
9) Out-of-bounds read (CVE-ID: CVE-2022-28615)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the ap_strcmp_match() function when processing an extremely large input buffer. A remote attacker can send a specially crafted HTTP request to the web server, trigger an out-of-bounds read error and read contents of memory on the system.
Note, the code distributed with the Apache HTTP Server cannot be coerced into such a call. The vulnerability can affect third-party modules or lua scripts that use ap_strcmp_match().
10) Out-of-bounds read (CVE-ID: CVE-2022-28614)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the ap_rwrite() function. A remote attacker can with the ability to force the server to reflect a very large input using ap_rwrite() or ap_rputs() (such as with mod_luas r:puts() function) can trigger an out-of-bounds read error and read read unintended memory on the system.
11) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-26377)
The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests in mod_proxy_ajp. A remote attacker can send a specially crafted HTTP request to the server and smuggle requests to the AJP server it forwards requests to.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
12) OS Command Injection (CVE-ID: CVE-2022-1292)
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation in the c_rehash script distributed by some operating systems. A remote attacker with ability to pass data to c_rehash script can and execute arbitrary OS commands with the privileges of the script.
