Document Management Xss Flaw: Accessing Sensitive Documents Exposed

Multiple Document Management Systems (DMSs) have been found to have cross-site scripting (XSS) vulnerabilities, which pose a serious risk to the security of sensitive documents. Specifically, vulnerabilities have been identified in ONLYOFFICE Workspace, OpenKM Document and Application, LogicalDOC, and Mayan EDMS. In ONLYOFFICE Workspace, a stored XSS vulnerability in the search function was discovered, while OpenKM DMS is vulnerable to persistent XSS that requires direct access to create a malicious note. LogicalDOC has multiple stored XSS vulnerabilities in its in-product messaging system, chat system, and document file name indexes. Additionally, Mayan EDMS has a stored XSS vulnerability in its tagging system, which can be exploited to steal session cookies and gain unauthorized access to stored documents. To mitigate these vulnerabilities, users of affected DMSs are advised to exercise caution when importing documents from unidentified sources, limit access for anonymous and suspicious users, and implement restrictions on certain features. Regular patching and updates are also essential to address these security flaws effectively.

Key Takeaways

• Multiple Document Management Systems (DMSs) such as ONLYOFFICE Workspace, OpenKM, LogicalDOC, and Mayan EDMS are affected by XSS vulnerabilities, which allow attackers to access sensitive documents.
• The success of the attacks depends on providing malicious documents, and the vulnerabilities exist in various features and systems of the DMSs.
• Attackers can exploit XSS vulnerabilities to gain unauthorized access, steal sensitive information, and even create privileged accounts.
• It is crucial for users of impacted DMSs to exercise caution when importing documents from unidentified or suspect sources, limit the creation of anonymous and suspicious users, and regularly update their systems to patch vulnerabilities and mitigate security risks.

Vulnerabilities in ONLYOFFICE

In the context of the pre-existing knowledge on multiple document management XSS flaws, one vulnerability identified is in ONLYOFFICE, specifically in version 12.1.0.1760. This vulnerability involves a stored XSS vulnerability in the search functionality, which allows attackers to access sensitive documents by exploiting a malicious document. The exploitation techniques for XSS vulnerabilities in ONLYOFFICE involve the attacker providing a malicious document that triggers the attack when accessed for indexing. However, it is important to note that the vulnerability in ONLYOFFICE has been fixed as of the latest update on 3/16/2023. This fix is significant as it mitigates the impact of the vulnerability on users‘ security and prevents unauthorized access to sensitive documents.

Vulnerabilities in OpenKM

OpenKM, a popular document and application platform, has been identified with vulnerabilities that allow for stored XSS conditions. These vulnerabilities can be exploited by attackers who have direct access to OpenKM, enabling them to create malicious notes that trigger the attack. The OpenKM DMS is susceptible to persistent XSS, with the vulnerabilities observed in the in-product messaging system, chat system, stored document file name indexes, and version comments. Successful exploitation of these XSS vulnerabilities has been observed in LogicalDOC Enterprise version 8.8.2 and Community version 8.7.3, often through guest access level frequently used for attacks against privileged users. To strengthen OpenKM security measures, it is recommended to limit the creation of anonymous and suspicious users, restrict access to features like chats and tagging to known users, and stay informed about security updates and fixes.

Vulnerabilities in LogicalDOC

LogicalDOC, another widely used document management system (DMS), has also been found to have multiple stored XSS vulnerabilities. These vulnerabilities have been observed in the in-product messaging system, chat system, stored document file name indexes, and version comments. Successful exploitation of these vulnerabilities has been identified in LogicalDOC Enterprise version 8.8.2 and Community version 8.7.3. Additionally, the guest access level is frequently utilized for attacks against privileged users. These vulnerabilities in LogicalDOC highlight the importance of implementing proper security measures to protect sensitive documents. Organizations using LogicalDOC should exercise caution when granting guest access and restrict access to features such as chats and tagging to known users. Regular patching and updates are crucial to mitigate these vulnerabilities and prevent unauthorized access to sensitive information.

Vulnerability in Mayan EDMS

The Mayan EDMS system has been identified as having a vulnerability that allows for stored XSS attacks. This vulnerability, identified as CVE-2022-47419, specifically targets the tagging system within Mayan EDMS. Attackers can exploit this vulnerability to execute malicious code and steal session cookies of authenticated administrators. By gaining access to these session cookies, attackers can bypass authentication and gain unauthorized access to stored documents within the system. This poses significant implications for document security, as attackers can potentially access sensitive and confidential information. The Mayan EDMS version 4.3.3 is vulnerable to this XSS flaw. It is imperative for organizations using Mayan EDMS to apply the necessary patches and updates to mitigate the risk of such attacks and protect their document management system from unauthorized access.

Importance of Patching and Updates

Patching and updating software systems is essential to safeguard against potential security vulnerabilities and ensure the integrity of sensitive information. The importance of timely patching and updates in preventing security breaches cannot be overstated. Vulnerability management plays a crucial role in maintaining the security of document management systems (DMSs). By regularly applying patches and updates, organizations can address known vulnerabilities and protect against potential exploits. This helps to mitigate security risks and prevent unauthorized access to sensitive documents. It is important for organizations to stay informed about security updates and fixes provided by DMS vendors. By doing so, they can proactively address any identified vulnerabilities and ensure the ongoing protection of their document management systems.

Frequently Asked Questions

How can an attacker exploit the XSS vulnerability in ONLYOFFICE Workspace?

To exploit the XSS vulnerability in ONLYOFFICE Workspace, an attacker can use a malicious document and take advantage of the stored XSS condition. By accessing a document saved in the DMS for indexing, the attacker can trigger the attack and potentially gain unauthorized access.

What is the impact of the XSS vulnerabilities in OpenKM Document and Application?

The XSS vulnerabilities in OpenKM Document and Application have the potential to result in data breaches and compromised user accounts. These vulnerabilities enable attackers to execute stored XSS attacks, leading to unauthorized access and manipulation of sensitive information.

Which features and systems in LogicalDOC are affected by the XSS vulnerabilities?

The XSS vulnerabilities in LogicalDOC affect various features and systems. These include the in-product messaging system, chat system, stored document file name indexes, and version comments. The vulnerabilities were observed in LogicalDOC Enterprise version 8.8.2 and Community version 8.7.3.

How does the XSS vulnerability in Mayan EDMS Tagging System work?

The XSS vulnerability in the Mayan EDMS tagging system allows attackers to execute malicious code by exploiting the in-product tagging system. By stealing the session cookie of an authenticated administrator, the attacker can gain access to stored documents and create privileged accounts. To prevent XSS attacks, it is important to regularly update the Mayan EDMS software and follow security best practices.

Why is patching and updating crucial in mitigating security risks in the affected DMSs?

Patching and updating are crucial in mitigating security risks in the affected DMSs. Regular updates help prevent attacks by addressing vulnerabilities. By staying informed about security updates and fixes, organizations can protect their sensitive information from unauthorized access.
