brighamandwomens.org
Boston's Brigham and Women's Hospital (BWH) is an international leader in virtually every area of medicine and has been the site of pioneering breakthroughs that have improved lives around the world. A major teaching hospital of Harvard Medical School, BWH has a legacy of excellence that continues to grow. With two outstanding hospitals, over 150 outpatient practices, and over 1,200 physicians, we serve patients from New England, throughout the United States, and from 120 countries around the world. The BWH name is a reflection of our history. In 1980 three of Boston’s oldest and most prestigious Harvard Medical School teaching hospitals - the Peter Bent Brigham Hospital, the Robert Breck Brigham Hospital, and the Boston Hospital for Women – merged to form Brigham and Women’s Hospital. As a national leader in improving health care quality and safety, we have helped to develop some of the industry’s best practices including computerized physician order entry (CPOE) to prevent medication errors. The CPOE is now a nationally-accepted safety practice. The BWH Biomedical Research Institute (BRI) is one of the most powerful biomedical research institutes in the world and the second largest recipient of National Institutes of Health (NIH) funding among independent hospitals in the United States. BWH has long had great success in research as measured by the number of important discoveries made, the size and scope of its research portfolio and the volume of publications annually. BWH is a training ground for physicians, nurses, and allied health professionals. We have 1,100 trainees in over 140 of the most sought after training programs in the world, and also host Harvard Medical School students in rotations throughout our programs. As our global health services expand, our clinical trainees have rich opportunities to contribute and learn in challenging environments around the world. Brigham and Women's Hospital is an EEO, AA, VEVRAA Employer.

Description
Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to versions 19.2.16, 20.3.14, and 21.0.1, there is a XSRF token leakage via protocol-relative URLs in angular HTTP clients. The vulnerability is a Credential Leak by App Logic that leads to the unauthorized disclosure of the Cross-Site Request Forgery (XSRF) token to an attacker-controlled domain. Angular's HttpClient has a built-in XSRF protection mechanism that works by checking if a request URL starts with a protocol (http:// or https://) to determine if it is cross-origin. If the URL starts with protocol-relative URL (//), it is incorrectly treated as a same-origin request, and the XSRF token is automatically added to the X-XSRF-TOKEN header. This issue has been patched in versions 19.2.16, 20.3.14, and 21.0.1. A workaround for this issue involves avoiding using protocol-relative URLs (URLs starting with //) in HttpClient requests. All backend communication URLs should be hardcoded as relative paths (starting with a single /) or fully qualified, trusted absolute URLs.

Description
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. An Uncontrolled Recursion vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft deep ASN.1 structures that trigger unbounded recursive parsing. This leads to a Denial-of-Service (DoS) via stack exhaustion when parsing untrusted DER inputs. This issue has been patched in version 1.3.2.

Description
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. An Integer Overflow vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft ASN.1 structures containing OIDs with oversized arcs. These arcs may be decoded as smaller, trusted OIDs due to 32-bit bitwise truncation, enabling the bypass of downstream OID-based security decisions. This issue has been patched in version 1.3.2.

Description
Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Prior to versions 7.0.13 and 8.0.2, working with large buffers in Lua scripts can lead to a stack overflow. Users of Lua rules and output scripts may be affected when working with large buffers. This includes a rule passing a large buffer to a Lua script. This issue has been patched in versions 7.0.13 and 8.0.2. A workaround for this issue involves disabling Lua rules and output scripts, or making sure limits, such as stream.depth.reassembly and HTTP response body limits (response-body-limit), are set to less than half the stack size.
