Improving security in the applications that drive the digital economy is a necessary undertaking, requiring ongoing collaboration between the public and private sectors.

Mattermost versions 8.1.x before 8.1.11, 9.3.x before 9.3.3, 9.4.x before 9.4.4, and 9.5.x before 9.5.2 fail to authenticate the source of certain types of post actions, allowing an authenticated attacker to create posts as other users via a crafted post action.

Mattermost Server versions 9.5.x before 9.5.2, 9.4.x before 9.4.4, 9.3.x before 9.3.3, 8.1.x before 8.1.11 don't limit the number of user preferences which allows an attacker to send a large number of user preferences potentially causing denial of service.

A Babuk variant has been involved in at least four attacks on VMware EXSi servers in the last six weeks, in one case demanding $140 million from a Chilean data center company.

So far this year, Ivanti has disclosed a total of 10 flaws — many of them critical — in its remote access products, and one in its ITSM product.

An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header frames we will process before closing a connection.

An April 2023 study from Kent State University found that remote workers are more likely to be vigilant of security threats and take actions to ward them off than their in-office counterparts.

Jackson County has suffered "significant disruptions within its IT systems," and its offices are closed.
