Adobe AEM ACS Common Exposure Scanner

Adobe AEM (Adobe Experience Manager) ACS Common is widely used across various industries to manage content and digital assets effectively. It is primarily utilized by web development teams, content creators, and digital marketers to enhance user experience and streamline content delivery. The platform assists in managing websites, mobile applications, and other forms of digital communication effectively across multiple channels. Companies rely on it to quickly implement changes, deploy content, and manage workflows associated with content creation and delivery. Furthermore, it is leveraged in larger organizations to ensure consistency in branding and messaging across different digital platforms. Its comprehensive functionalities support content lifecycle management, including creating, editing, publishing, and archiving digital content.

An exposure vulnerability in Adobe AEM ACS Common can lead to the unintended access of sensitive web pages. When specific pages associated with the ACS Common component are not secured properly, they become publicly accessible, potentially providing valuable information to unauthorized users. Such exposures might offer insights into the internal configurations, workflows, or indexing mechanisms of a digital asset management system. They can occur due to misconfigurations or oversight during the deployment and configuration processes. Identifying these issues promptly is crucial as they might provide attackers with an entry point to further explore and exploit potential weaknesses. The scanner aims to help organizations quickly pinpoint and address these exposures, ensuring that sensitive pages remain secure from unauthorized view or access.

The technical details of this vulnerability involve the exposure of Adobe AEM ACS Common pages with URLs such as '/etc/acs-commons/jcr-compare.html' and '/etc/acs-commons/oak-index-manager.html'. These endpoints, when exposed, can divulge sensitive information about the JCR structure or index information. Matchers within this scanner look for specific titles in the webpage, such as 'Version Compare | ACS AEM Commons', indicating that the page is exposed and accessible by unauthorized users. Since such pages can reveal configuration or workflow information, they must be shielded behind authentication mechanisms. The template uses a GET request method, indicating how the exposure is checked and why this swift detection matters in safeguarding digital communication channels.

If exploited, exposure vulnerabilities can lead to unauthorized access to sensitive configuration pages and workflow systems. Malicious entities might gather information on how internal systems operate, which could be a precursor to more serious attacks. It may lead to further vulnerabilities being exploited due to insights gathered from exposed data, facilitating attacks like SQL Injection, Path Traversal, or even Remote Code Execution. The risk of information leakage might compromise the security posture of an organization’s digital assets. It further opens avenues for phishing attacks or social engineering, using the exposed information to craft convincing yet malicious attempts to extract further data or gain deeper system access.
