One Identity Secure Password Extension Privilege Escalation (CVE-2025-27582)

Cyberis has discovered a local privilege escalation (LPE) vulnerability - CVE-2025-27582 - in One Identity Secure Password Extension x64 v5.14.3.1, a component of One Identity Password Manager. By abusing the Password Self-Service feature available on the Windows lock screen, an attacker can bypass security restrictions, launch a SYSTEM-privileged print dialog, and ultimately gain a SYSTEM shell. This vulnerability requires only local access and is trivially exploitable in environments where this software is deployed. An attacker can escalate to SYSTEM directly from the logon screen—without requiring valid credentials.

Microsoft Bookings – Facilitating Impersonation

Microsoft Bookings introduces a significant security risk by allowing end users to create fully functional Entra accounts without administrative oversight. These accounts, tied to shared Booking pages, can be exploited for impersonation, phishing, and email hijacking. Attackers could leverage this functionality to bypass security measures, gain unauthorised access to sensitive resources, and facilitate lateral movement within an organisation. Our blog explores these weaknesses in detail and provides recommendations for detection and mitigation.

Exploiting KeePass CVE-2023-32784

KeePass is a popular open-source password manager which allows users to securely store and manage their passwords in an encrypted database. On May 10 2023 a high risk vulnerability was discovered. This vulnerability allows an attacker with access to the system where KeePass is running to exploit the flaw by analysing a memory dump to extract the master password to the database. The memory dump containing the password can include KeePass process dump, RAM dump of the entire system, hibernation files, or swap files. In this article we will extract the password from KeePass process dump.
