Mazars USA LLPBreach60310/2025
Rankiteo Explanation :
Attack with significant impact with internal employee data leaks

Description: Mazars USA LLP, a certified public accounting firm, faced regulatory action by the New York Attorney General (NY AG) for failing to secure unencrypted sensitive personal data, including **Social Security numbers, financial records, and tax documents** of clients and employees. The breaches occurred due to inadequate cybersecurity measures, such as **lack of encryption, weak access controls, and failure to monitor third-party vendors**. While the article does not specify a direct data leak of customer information, the exposed data—if compromised—could enable identity theft, financial fraud, or reputational harm. The NY AG’s settlement required Mazars to pay **$60,000 in penalties** and implement stricter security protocols, including encryption, multi-factor authentication (MFA), and vendor risk assessments. The incident highlights vulnerabilities in handling **highly sensitive financial and personal data**, particularly in sectors like accounting where trust and confidentiality are critical. The breach did not result in confirmed theft but posed significant risks to **employee and client privacy**, warranting regulatory intervention.

WeiserMazars, LLCBreach85410/2012
Rankiteo Explanation :
Attack with significant impact with customers data leaks

Description: On October 10, 2012, Accume Partners suffered a data breach due to a stolen laptop belonging to WeiserMazars, LLC, an affiliated third-party service provider. The incident was reported by the California Office of the Attorney General on December 10, 2012. The breach exposed sensitive personal information of plan participants, specifically **names and Social Security numbers (SSNs)**. The compromised data belonged to individuals associated with Accume Partners’ retirement or benefit plans, raising concerns over potential identity theft, financial fraud, or misuse of the exposed SSNs. While the exact number of affected individuals was not specified in the report, the exposure of such highly sensitive information posed a significant risk to the privacy and financial security of the impacted participants. The breach stemmed from the physical theft of an unencrypted or inadequately secured device, highlighting vulnerabilities in data protection protocols involving third-party vendors.

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.
