Stored Cross-Site Scripting (XSS) vulnerability discovered in WordPress Comment Engine Pro plugin (versions <= 1.0), could be exploited by users with Editor or higher role.

A great many readers this month reported receiving alerts that their Social Security Number, name, address and other personal information were exposed in a breach at a little-known but aptly-named consumer data broker called NationalPublicData.com. This post examines what we know about a breach that has exposed hundreds of millions of consumer records. We'll also take a closer look at the data broker that got hacked -- a background check company founded by an actor and retired sheriff's deputy from Florida.

The Apache Spark UI offers the possibility to enable ACLs via the configuration option spark.acls.enable. With an authentication filter, this checks whether a user has access permissions to view or modify the application. If ACLs are enabled, a code path in HttpSecurityFilter can allow someone to perform impersonation by providing an arbitrary user name. A malicious user might then be able to reach a permission check function that will ultimately build a Unix shell command based on their input, and execute it. This will result in arbitrary shell command execution as the user Spark is currently running as. This issue was disclosed earlier as CVE-2022-33891, but incorrectly claimed version 3.1.3 (which has since gone EOL) would not be affected. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. Users are recommended to upgrade to a supported version of Apache Spark, such as version 3.4.0.

A `NULL` pointer can be dereferenced when signatures are being verified on PKCS7 `signed` or `signedAndEnveloped` data. In case the hash algorithm used for the signature is known to the OpenSSL library but the implementation of the hash algorithm is not available the digest initialization will fail. There is a missing check for the return value from the initialization function which later leads to invalid usage of the digest API most likely leading to a crash. The unavailability of an algorithm can be caused by using FIPS enabled configuration of providers or more commonly by not loading the legacy provider. PKCS7 data is processed by the SMIME library calls and also by the time stamp (TS) library calls. The TLS implementation in OpenSSL does not call these functions however third party applications would be affected if they call these functions to verify signatures on untrusted data.

The library provides a safe public API `unpack` to cast `u8` array to arbitrary types, which can cause to undefined behaviors. The length check of array can only prevent out-of-bound access on the return type. However, it can't prevent misaligned pointer when casting `u8` pointer to a type aligned to larger bytes. For example, if we assign `u16` to `T`, **misaligned raw pointer dereference** could happen and cause to panic. Even if we pass the type aligned to same byte as `u8` (e.g., `bool`), it could construct a illegal type since `bool` can only have 0 or 1 as bit patterns, which is also an undefined behavior. The further exploits of the bug here are still not clear, so we would report this issue as unsound. The details of PoC to reproduce undefined behavior are provided in the [issue](https://github.com/solana-labs/solana-program-library/issues/5243).

Ubuntu Security Notice 7060-1 - It was discovered that EDK II did not check the buffer length in XHCI, which could lead to a stack overflow. A local attacker could potentially use this issue to cause a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. Laszlo Ersek discovered that EDK II incorrectly handled recursion. A remote attacker could possibly use this issue to cause EDK II to consume resources, leading to a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.

Multiple security vulnerabilities have been discovered in various services, including Honeywell Experion distributed control system (DCS) and QuickBlox, that, if successfully exploited, could result in severe compromise of affected systems. Dubbed Crit.IX, the nine flaws in the Honeywell Experion DCS platform allow for "unauthorized remote code execution, which means an attacker would have

New web targets for the discerning hacker

The Ecwid Ecommerce Shopping Cart plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 6.10.23. This is due to missing or incorrect nonce validation on the ecwid_update_plugin_params function. This makes it possible for unauthenticated attackers to update plugin options granted they can trick a site administrator into performing an action such as clicking on a link.

The function check_is_login_page() uses headers for the IP check, which can be easily spoofed.
