Vulnerabilities

Issue summary: Calling the OpenSSL API function SSL_free_buffers may cause<br /> memory to be accessed that was previously freed in some situations<br /> <br /> Impact summary: A use after free can have a range of potential consequences such<br /> as the corruption of valid data, crashes or execution of arbitrary code.<br /> However, only applications that directly call the SSL_free_buffers function are<br /> affected by this issue. Applications that do not call this function are not<br /> vulnerable. Our investigations indicate that this function is rarely used by<br /> applications.<br /> <br /> The SSL_free_buffers function is used to free the internal OpenSSL buffer used<br /> when processing an incoming record from the network. The call is only expected<br /> to succeed if the buffer is not currently in use. However, two scenarios have<br /> been identified where the buffer is freed even when still in use.<br /> <br /> The first scenario occurs where a record header has been received from the<br /> network and processed by OpenSSL, but the full record body has not yet arrived.<br /> In this case calling SSL_free_buffers will succeed even though a record has only<br /> been partially processed and the buffer is still in use.<br /> <br /> The second scenario occurs where a full record containing application data has<br /> been received and processed by OpenSSL but the application has only read part of<br /> this data. Again a call to SSL_free_buffers will succeed even though the buffer<br /> is still in use.<br /> <br /> While these scenarios could occur accidentally during normal operation a<br /> malicious attacker could attempt to engineer a stituation where this occurs.<br /> We are not aware of this issue being actively exploited.<br /> <br /> The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.

The MultiManager WP – Manage All Your WordPress Sites Easily plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.0.5. This is due to the user impersonation feature inappropriately determining the current user via user-supplied input. This makes it possible for unauthenticated attackers to generate an impersonation link that will allow them to log in as any existing user, such as an administrator. NOTE: The user impersonation feature was disabled in version 1.1.0 and re-enabled with a patch in version 1.1.2.

A vulnerability was found in VIWIS LMS 9.11. It has been classified as critical. Affected is an unknown function of the component Print Handler. The manipulation leads to missing authorization. It is possible to launch the attack remotely. A user with the role learner can use the administrative print function with an active session before and after an exam slot to access the entire exam including solutions in the web application. It is recommended to apply a patch to fix this issue.

The Royal Elementor Addons and Templates plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin&amp;#39;s Countdown widget in all versions up to, and including, 1.7.1001 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Royal Elementor Addons and Templates plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin&amp;#39;s Form Builder widget in all versions up to, and including, 1.7.1001 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Royal Elementor Addons and Templates plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Google Maps widget in all versions up to, and including, 1.7.1001 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The AFI – The Easiest Integration Plugin plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg &amp; remove_query_arg without appropriate escaping on the URL in all versions up to, and including, 1.92.0. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Cross-site scripting vulnerability exists in VK All in One Expansion Unit versions prior to 9.100.1.0. If this vulnerability is exploited, an arbitrary script may be executed on the web browser of the user who is accessing the web site using the product.

CWE-400: An Uncontrolled Resource Consumption vulnerability exists that could cause the device to become<br /> unresponsive resulting in communication loss when a large amount of IGMP packets is present in the network.

CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability exists that could<br /> cause a potential arbitrary code execution after a successful Man-In-The-Middle attack followed by sending a<br /> crafted Modbus function call to tamper with memory area involved in memory size computation.

CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability exists that could<br /> cause a potential arbitrary code execution after a successful Man-In-The Middle attack followed by sending a<br /> crafted Modbus function call to tamper with memory area involved in the authentication process.

CWE-20: Improper Input Validation vulnerability exists that could lead to loss of confidentiality of controller memory<br /> after a successful Man-In-The-Middle attack followed by sending a crafted Modbus function call used to tamper<br /> with memory.
