AlienVault OTX Vulnerabilities

AlienVault OTX Malware

modern-image-gallery-app

A vulnerability was detected in SourceCodester Modern Image Gallery App 1.0. Affected by this vulnerability is an unknown functionality of the file upload.php. The manipulation of the argument filename results in cross site scripting. The attack may be launched remotely. The exploit is now public and may be used.

CVE-2026-3070 is a cross-site scripting (XSS) vulnerability identified in the SourceCodester Modern Image Gallery App version 1.0. The vulnerability is located in the upload.php script, specifically related to the handling of the 'filename' parameter. Due to insufficient input validation or sanitization, an attacker can manipulate this parameter to inject malicious JavaScript code. When a victim accesses a crafted URL or interacts with the vulnerable functionality, the injected script executes in their browser context. This can lead to session hijacking, defacement, or redirection to malicious sites. The vulnerability is remotely exploitable without requiring any authentication or privileges, but user interaction is necessary to trigger the attack. The CVSS 4.0 base score is 5.3, reflecting medium severity, with attack vector network, low attack complexity, no privileges required, user interaction required, and limited impact on integrity and confidentiality. No official patches or fixes have been published as of now, and while the exploit code is publicly available, no active exploitation campaigns have been reported. The vulnerability affects only version 1.0 of the Modern Image Gallery App, which is a web-based application commonly used for image management and display. The lack of secure coding practices around file upload parameters is the root cause, highlighting the importance of rigorous input validation and output encoding in web applications.

CVE-2026-3070: Cross Site Scripting in SourceCodester Modern Image Gallery App

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.

CVE-2025-70457 is a critical Remote Code Execution (RCE) vulnerability identified in the Sourcecodester Modern Image Gallery App version 1.0, specifically within the gallery/upload.php file handling image uploads. The vulnerability arises because the application fails to properly validate the contents of uploaded files, relying instead on user-supplied MIME types and preserving the original file extensions without verification. This flaw allows an unauthenticated attacker to craft a malicious file containing PHP code, spoof its MIME type as an image, and upload it to the server. Since the application saves the file with the attacker-controlled extension and does not sanitize or restrict executable code, the attacker can then execute arbitrary PHP code on the server. This leads to full system compromise, including the ability to read, modify, or delete data, install backdoors, or pivot within the network. The vulnerability is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) and has a CVSS v3.1 base score of 9.8, reflecting its critical severity. The attack vector is network-based, requires no authentication or user interaction, and affects the confidentiality, integrity, and availability of the affected system. Although no known exploits have been reported in the wild yet, the straightforward exploitation method and severe impact make it a significant threat. No official patches have been released at the time of publication, increasing the urgency for organizations to implement mitigations.
