This security bulletin contains information about 5 secuirty vulnerabilities.
1) Cross-site scripting (CVE-ID: CVE-2022-34305)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data passed to the form authentication example in the examples web application. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
2) Resource management error (CVE-ID: CVE-2022-2048)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application when handling invalid HTTP/2 requests. A remote attacker can send specially crafted requests to the server and perform a denial of service (DoS) attack.
3) OS Command Injection (CVE-ID: CVE-2022-2068)
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.
The vulnerability exists due to incomplete fix for #VU62765 (CVE-2022-1292).
4) 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.
5) Code Injection (CVE-ID: CVE-2021-3918)
The disclosed vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to insufficient sanitization of user-supplied data during the validation of a JSON object. A remote attacker can pass a specially crafted JSON file for validation and execute arbitrary code.
