AlienVault OTX Vulnerabilities

AlienVault OTX Malware

User Interface (UI) Misrepresentation of Critical Information vulnerability in OpenText™ Directory Services allows Cache Poisoning. 

The vulnerability could be exploited by a bad actor to inject manipulated text into the OpenText application, potentially misleading users.

This issue affects Directory Services: from 20.4.1 through 25.2.

CVE-2026-1658 identifies a vulnerability classified under CWE-451 (User Interface Misrepresentation of Critical Information) in OpenText™ Directory Services, specifically affecting versions from 20.4.1 through 25.2. The flaw allows an attacker to perform cache poisoning, injecting manipulated or falsified text into the application's user interface. This misrepresentation can deceive users by displaying incorrect or misleading information, which may lead to improper actions or decisions. The vulnerability does not require any authentication or privileges, making it accessible to remote attackers over the network. However, user interaction is necessary to trigger the UI misrepresentation, as the manipulated content must be viewed by the user. The CVSS 4.0 base score is 5.3 (medium severity), reflecting the moderate impact on confidentiality and availability, with integrity affected due to falsified UI content. The vulnerability does not directly compromise system control or data confidentiality but undermines trust in the displayed information, which can have downstream operational or security consequences. No patches or exploit code are currently publicly available, and no known exploits have been reported in the wild. The vulnerability stems from insufficient validation or sanitization of data that is cached and subsequently rendered in the UI, enabling attackers to inject misleading content. This can be leveraged in social engineering attacks or to disrupt normal directory service operations by confusing users or administrators.
