Rankiteo Explanation :
Attack with significant impact with internal employee data leaks

Description: The California Office of the Attorney General reported a data breach involving Wells Fargo Bank, N.A. on May 5, 2022. The breach occurred on December 31, 2021, when a Wells Fargo employee emailed an encrypted file containing personal information to their personal email address, affecting an unspecified number of individuals.

Wells Fargo Bank, N.A.Breach85411/2019
Rankiteo Explanation :
Attack with significant impact with customers data leaks

Description: On November 6, 2019, Wells Fargo Bank, N.A. discovered a data breach linked to KDW Automotive, where an employee mistakenly sent an email containing sensitive personal information to an unintended financial institution. The exposed data included names and Social Security numbers of affected individuals, potentially putting them at risk of identity theft or fraud. The breach was reported to the California Office of the Attorney General in April 2020, highlighting a lapse in data handling protocols. While the incident did not involve malicious cyber activity, the unauthorized disclosure of personally identifiable information (PII) posed significant privacy concerns. The breach underscored the need for stricter email security measures and employee training to prevent similar errors in the future. No evidence suggested the data was misused, but the exposure alone created reputational and compliance risks for Wells Fargo.

Wells Fargo Bank, N.A.Breach8545/2022
Rankiteo Explanation :
Attack with significant impact with customers data leaks

Description: The Vermont Office of the Attorney General disclosed a data breach at Wells Fargo Bank on **September 19, 2024**, stemming from unauthorized access to **customer personal information** by a **former employee** between **May 2022 and March 2023**. The breach involved the misuse of internal systems to exfiltrate sensitive data, though the exact number of affected individuals remains undisclosed. The compromised information may include personally identifiable details, exposing customers to potential identity theft, financial fraud, or phishing attacks. The prolonged duration of the breach—nearly a year—suggests systemic vulnerabilities in access controls and post-employment monitoring. While Wells Fargo has not confirmed the scope of the stolen data, the incident underscores risks associated with insider threats and delayed detection. Regulatory scrutiny and customer notifications are expected, with potential reputational damage and legal repercussions for the bank.

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.
