Breach
Rankiteo Explanation
Attack with significant impact with customers data leaks
Description: Thomson Reuters provides customers with products such as the business-to-business media tool Reuters Connect, legal research service and database Westlaw, the tax automation system ONESOURCE, online research suite of editorial and source materials Checkpoint, and other tools. The size of the open database the team discovered corresponds with the company using ElasticSearch, a data storage favored by enterprises dealing with extensive, constantly updated volumes of data. Media giant with $6.35 billion in revenue left at least three of its databases open At least 3TB of sensitive data exposed including Thomson Reuters plaintext passwords to third-party servers The data company collects is a treasure trove for threat actors, likely worth millions of dollars on underground criminal forums The company has immediately fixed the issue, and started notifying their customers Thomson Reuters downplayed the issue, saying it affects only a “small subset of Thomson Reuters Global Trade customers” The dataset was open for several days – malicious bots are capable of discovering instances within mere hours Threat actors could use the leak for attacks, from social engineering attacks to ransomware

Cyber Attack
Rankiteo Explanation
Attack with significant impact with internal employee data leaks
Description: In retaliation for a cyber attack by Russia against the Ukrainian telecom giant Kyivstar, hackers associated with Ukraine's primary intelligence agency have infiltrated the computer systems of a Moscow-based internet provider, Reuters reports. The hackers, allegedly linked to Ukraine's spy agency, erased 20 terabytes of data from M9 Telecom, a relatively small Russian internet and TV provider, resulting in some Moscow residents experiencing internet service disruptions. Despite the hacking group's assertion that the company's website had been destroyed, the extent of the successful breach could not be independently verified by Reuters.

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.
