python-cryptography: SSH certificate encoding/parsing incompatibility with OpenSSH

The cryptography package before 41.0.2 for Python mishandles SSH certificates that have critical options.

An issue was discovered in OpenNDS Captive Portal before version 10.1.2. It has a do_binauth NULL pointer dereference that be triggered with a crafted GET HTTP request with a missing User-Agent HTTP header. Triggering this issue results in crashing OpenNDS (a Denial-of-Service condition). The issue occurs when the client is about to be authenticated, and can be triggered only when the BinAuth option is set. Affected OpenNDS Captive Portal before version 10.1.2 fixed in OpenWrt master, OpenWrt 23.05 and OpenWrt 22.03 on 28. August 2023 by updating OpenNDS to version 10.1.3.

OpenNDS, as used in Sierra Wireless ALEOS before 4.17.0.12 and other products, allows remote attackers to cause a denial of service (NULL pointer dereference, daemon crash, and Captive Portal outage) via a GET request to /opennds_auth/ that lacks a custom query string parameter and client-token.

An issue was discovered in OpenNDS Captive Portal before version 10.1.2. It has a show_preauthpage NULL pointer dereference that can be triggered with a crafted GET HTTP with a missing User-Agent header. Triggering this issue results in crashing OpenNDS (a Denial-of-Service condition). This problem was fixed in OpenWrt master, OpenWrt 23.05 and OpenWrt 22.03 on 28. August 2023 by updating OpenNDS to version 10.1.3.

An issue was discovered in OpenNDS Captive Portal before version 10.1.2. When the custom unescape callback is enabled, attackers can execute arbitrary OS commands by inserting them into the URL portion of HTTP GET requests. Affected OpenNDS Captive Portal before version 10.1.2 fixed in OpenWrt master, OpenWrt 23.05 and OpenWrt 22.03 on 28. August 2023 by updating OpenNDS to version 10.1.3.

An issue was discovered in OpenNDS Captive Portal before version 10.1.2. It has a try_to_authenticate NULL pointer dereference that can be triggered with a crafted GET HTTP with a missing client token query string parameter. Triggering this issue results in crashing OpenNDS (a Denial-of-Service condition). Affected OpenNDS Captive Portal before version 10.1.2 fixed in OpenWrt master, OpenWrt 23.05 and OpenWrt 22.03 on 28. August 2023 by updating OpenNDS to version 10.1.3.

An issue was discovered in OpenNDS Captive Portal before version 10.1.2. It has a NULL pointer dereference in preauthenticated() that can be triggered with a crafted GET HTTP request with a missing redirect query string parameter. Triggering this issue results in crashing OpenNDS (a Denial-of-Service condition).

A directory traversal vulnerability in Valve Counter-Strike 8684 allows a client (with remote control access to a game server) to read arbitrary files from the underlying server via the motdfile console variable.

An issue was discovered in Webmin 2.021. A Stored Cross-Site Scripting (XSS) vulnerability was discovered in the System Logs Viewer functionality. The vulnerability allows an attacker to store a malicious payload in the configuration field, triggering the execution of the payload when saving the configuration or when accessing the System Logs Viewer page.

An issue was discovered in Webmin 2.021. A Stored Cross-Site Scripting (XSS) vulnerability was discovered in the configuration settings of the system logs functionality. The vulnerability allows an attacker to store an XSS payload in the configuration settings of specific log files. This results in the execution of that payload whenever the affected log files are accessed.

An issue was discovered in Webmin 2.021. A Reflected Cross-Site Scripting (XSS) vulnerability was discovered in the package search functionality. The vulnerability allows an attacker to inject a malicious payload in the "Search for Package" field, which gets reflected back in the application's response, leading to the execution of arbitrary JavaScript code within the context of the victim's browser.

An issue was discovered in Webmin 2.021. A Cross-Site Scripting (XSS) vulnerability was discovered in the HTTP Tunnel functionality when handling third-party domain URLs. By providing a crafted URL from a third-party domain, an attacker can inject malicious code. leading to the execution of arbitrary JavaScript code within the context of the victim's browser.

An issue was discovered in Webmin 2.021. A Stored Cross-Site Scripting (XSS) vulnerability was discovered in the Users and Groups functionality. The vulnerability occurs when an authenticated user adds a new user and inserts an XSS payload into the user's real name.

An issue was discovered in Webmin 2.021. A Cross-site Scripting (XSS) Bypass vulnerability was discovered in the file upload functionality. Normally, the application restricts the upload of certain file types such as .svg, .php, etc., and displays an error message if a prohibited file type is detected. However, by following certain steps, an attacker can bypass these restrictions and inject malicious code.

An issue was discovered in Webmin 2.021. The download functionality allows an attacker to exploit a Cross-Site Scripting (XSS) vulnerability. By providing a crafted download path containing a malicious payload, an attacker can inject arbitrary code, which is then executed within the context of the victim's browser when the download link is accessed.

An issue was discovered in Webmin 2.021. A Stored Cross-Site Scripting (XSS) vulnerability was discovered in the Users and Groups functionality, allowing an attacker to store a malicious payload in the Group Name field when creating a new group.

An issue was discovered in Webmin 2.021. One can exploit a stored Cross-Site Scripting (XSS) attack to achieve Remote Command Execution (RCE) through the Users and Group's real name parameter.

Thymeleaf through 3.1.1.RELEASE, as used in spring-boot-admin (aka Spring Boot Admin) through 3.1.1 and other products, allows sandbox bypass via crafted HTML. This may be relevant for SSTI (Server Side Template Injection) and code execution in spring-boot-admin if MailNotifier is enabled and there is write access to environment variables via the UI.

In OpenBGPD before 8.1, incorrect handling of BGP update data (length of path attributes) set by a potentially distant remote actor may cause the system to incorrectly reset a session. This is fixed in OpenBSD 7.3 errata 006.
