Overview<\/strong><\/p>\n

The Common Vulnerabilities and Exposures system has identified a significant vulnerability, designated CVE-2025-54223, existing in InCopy versions 20.4, 19.5.4, and earlier. This vulnerability is notably severe due to its potential to enable an attacker to execute arbitrary code in the context of the current user. The implication of this is that the vulnerability could be exploited to take control<\/a> of an affected system or to exfiltrate sensitive data. It is crucial for organizations and individuals utilizing InCopy to be aware of this threat and to take the necessary steps to mitigate it.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-54223
\nSeverity: High (7.8 CVSS Score)
\nAttack Vector: Local
\nPrivileges Required: None
\nUser Interaction: Required
\nImpact: Potential system<\/a> compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

InCopy | 20.4 and earlier
\nInCopy | 19.5.4 and earlier<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability, known as a Use After Free vulnerability, exploits a specific type of programming error where the software uses memory space after it has been freed or de-allocated. This can lead to a variety of problematic outcomes including crashing the program, producing incorrect results, or, in this case, allowing a malicious actor to insert and execute arbitrary code<\/a>.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how this vulnerability might be exploited. In this example, a malicious payload is embedded within a document file that a user<\/a> is tricked into opening:<\/p>\n

POST \/openDocument HTTP\/1.1\nHost: vulnerableInCopy.example.com\nContent-Type: application\/json\n{ \"document\": {\n\"header\": \"normal_header_data\",\n\"body\": \"normal_body_data\",\n\"footer\": \"normal_footer_data\",\n\"malicious_payload\": \"code_to_be_executed_after_free()\"\n}\n}<\/code><\/pre>\n
In the above HTTP request, the malicious payload (“code_to_be_executed_after_free()”) is placed within the document object. When the document is opened in a vulnerable version of InCopy, the payload gets executed after the memory containing the document has been freed, leading to arbitrary code<\/a> execution.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
Users are advised to apply the vendor patch as soon as possible to mitigate the vulnerability. As a temporary measure, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to monitor network traffic and alert or block suspicious activities.<\/p>\n","protected":false},"excerpt":{"rendered":"
