Rankiteo Explanation
Attack threatening the organization’s existence
Description: In January 2023, Oslo-based DNV a leading global maritime classification society and risk management provider fell victim to a ransomware attack on January 7, forcing the shutdown of IT servers linked to its ShipManager system. The incident disrupted operations for 70 customers, impacting approximately 1,000 vessels reliant on the system for navigation, safety, and compliance management. DNV initiated daily communications with affected clients, providing updates from ongoing forensic investigations. While the attack caused significant operational disruptions potentially halting vessel management, logistical coordination, and regulatory compliance the company did not confirm whether sensitive customer or proprietary data was exfiltrated. The shutdown of critical IT infrastructure posed risks to maritime safety, supply chain continuity, and DNV’s reputation as a trusted industry authority. Recovery efforts focused on restoring systems while mitigating further propagation of the ransomware.

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. The `username` value can be echoed back without proper contextual encoding when authentication fails. An attacker can execute script in the login page context. This issue has been fixed in version 2.19.2.
Risk Information
cvss3
Base: 5.4
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.
