Mazars USA LLP
Breach
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, LLC
Breach
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
Typemill is a flat-file, Markdown-based CMS designed for informational documentation websites. A reflected Cross-Site Scripting (XSS) exists in the login error view template `login.twig` of versions 2.19.1 and below.

Risk Information

Severity: LOW
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N
Description
A DOM-based Cross-Site Scripting (XSS) vulnerability exists in the DomainCheckerApp class within domain/script.js of Sourcecodester Domain Availability Checker v1.0. The vulnerability occurs because the application improperly handles user-supplied data in the createResultElement method by using the unsafe innerHTML property to render domain search results.
Description
A Remote Code Execution (RCE) vulnerability exists in Sourcecodester Modern Image Gallery App v1.0 within the gallery/upload.php component. The application fails to properly validate uploaded file contents. Additionally, the application preserves the user-supplied file extension during the save process. This allows an unauthenticated attacker to upload arbitrary PHP code by spoofing the MIME type as an image, leading to full system compromise.
Description
A UNIX symbolic link following issue in the jailer component in Firecracker version v1.13.1 and earlier and 1.14.0 on Linux may allow a local host user with write access to the pre-created jailer directories to overwrite arbitrary host files via a symlink attack during the initialization copy at jailer startup, if the jailer is executed with root privileges. To mitigate this issue, users should upgrade to version v1.13.2 or 1.14.1 or above.

Description
An information disclosure vulnerability exists in the /srvs/membersrv/getCashiers endpoint of the Aptsys gemscms backend platform thru 2025-05-28. This unauthenticated endpoint returns a list of cashier accounts, including names, email addresses, usernames, and passwords hashed using MD5. As MD5 is a broken cryptographic function, the hashes can be easily reversed using public tools, exposing user credentials in plaintext. This allows remote attackers to perform unauthorized logins and potentially gain access to sensitive POS operations or backend functions.
