CVE-2025-30298 is a stack-based buffer overflow vulnerability identified in Adobe Framemaker versions 2020.8, 2022.6, and earlier. The vulnerability arises from improper handling of input data when processing Framemaker files, allowing an attacker to overwrite the stack memory. This can lead to arbitrary code execution within the context of the current user. Exploitation requires the victim to open a maliciously crafted Framemaker file, making user interaction mandatory. The vulnerability does not require any prior authentication, increasing its risk profile. The CVSS v3.1 base score is 7.8, reflecting high severity due to the combination of local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), and user interaction (UI:R). The impact covers confidentiality, integrity, and availability, as arbitrary code execution could lead to data theft, system compromise, or denial of service. Although no known exploits have been reported in the wild yet, the vulnerability's nature and Adobe Framemaker's widespread use in technical documentation and publishing make it a significant threat. No official patches were linked at the time of reporting, emphasizing the need for vigilance and interim mitigations.

The exploitation of CVE-2025-30298 can have severe consequences for organizations relying on Adobe Framemaker for technical documentation and publishing. Successful attacks can lead to arbitrary code execution, enabling attackers to steal sensitive information, alter or destroy data, install malware, or disrupt operations. Since the vulnerability executes code with the current user's privileges, the impact depends on the user's access level; administrative users could face full system compromise. The requirement for user interaction (opening a malicious file) means social engineering or phishing campaigns could be used to deliver the exploit. This vulnerability threatens confidentiality, integrity, and availability of affected systems, potentially leading to data breaches, intellectual property theft, and operational downtime. Organizations in sectors such as aerospace, defense, manufacturing, and publishing, which heavily use Framemaker, are particularly at risk. The absence of known exploits currently provides a window for proactive mitigation before widespread attacks occur.

1. Monitor Adobe's official channels for patches addressing CVE-2025-30298 and apply them immediately upon release. 2. Until patches are available, implement strict controls on the sources of Framemaker files, blocking or quarantining files from untrusted or unknown origins. 3. Educate users about the risks of opening unsolicited or suspicious Framemaker files, emphasizing caution with email attachments and downloads. 4. Employ application whitelisting and sandboxing techniques to limit Framemaker's ability to execute arbitrary code or interact with critical system components. 5. Use endpoint detection and response (EDR) solutions to monitor for unusual behaviors indicative of exploitation attempts. 6. Restrict user privileges to the minimum necessary to reduce the impact of potential code execution. 7. Maintain regular backups of critical documentation and systems to enable recovery in case of compromise. 8. Consider network segmentation to isolate systems running Framemaker from sensitive or critical infrastructure. These targeted steps go beyond generic advice by focusing on controlling file sources, user education, and containment strategies specific to the nature of this vulnerability.
