Mercy Health Global Score (TPRM)XXXX

Description: The California Office of the Attorney General disclosed a data breach affecting **Bon Secours Health System, Inc.** in August 2016. The incident occurred between **April 18–21, 2016**, when a third-party vendor, **R-C Healthcare Management**, inadvertently left files containing sensitive patient data exposed on the internet. The compromised information included **names, health insurance details, Social Security numbers, and clinical records** of unspecified individuals. The breach stemmed from misconfigured access controls, allowing unauthorized exposure of protected health information (PHI). While the exact number of affected patients was not specified, the exposure posed significant risks of identity theft, financial fraud, and privacy violations. The vendor’s negligence in securing the data led to potential long-term repercussions for the impacted individuals, including reputational harm to Bon Secours and regulatory scrutiny under healthcare data protection laws like **HIPAA**. No evidence of malicious exploitation was confirmed, but the unauthorized accessibility alone constituted a severe lapse in data security protocols.
Description: Bon Secours Health System, based in Marriottsville, Md., suffered from a data breach incident after that 655,000 patients health information were exposed as a result of an error made by one of its business associates. The compromised information included names, social security numbers, insurance and banking information, and some clinical data. Bon Secours conducted a two-month internal investigation of the incident, and offered a year of credit monitoring and identity theft protection services without charge.
Description: Mercy Health Lorain Hospital Laboratory experienced HIPAA breach due to contractor invoice printing error. No actual or attempted access or misuse of patient or guarantor information has been discovered. Batches of medical invoices created and mailed by RCM’s contracted mailing vendor were printed incorrectly. Instead of the name, street address, city, state, and zip code of the patient (or his/her guarantor) appearing in the clear address “window” of the envelope, what actually appeared were names, street addresses, and Social Security numbers.

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.
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.
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.
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.
Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. In versions from 8.0.0 to before 8.0.2, a NULL dereference can occur when the entropy keyword is used in conjunction with base64_data. This issue has been patched in version 8.0.2. A workaround involves disabling rules that use entropy in conjunction with base64_data.
