A library injection vulnerability exists in Microsoft Outlook 16.83.3 for macOS. A specially crafted library can leverage Outlook's access privileges, leading to a permission bypass. A malicious application could inject a library and start the program to trigger this vulnerability and then make use of the vulnerable application's permissions.

HCL Traveler for Microsoft Outlook (HTMO) is susceptible to a control flow vulnerability. The application does not sufficiently manage its control flow during execution, creating conditions in which the control flow can be modified in unexpected ways.

Microsoft Outlook Spoofing Vulnerability

A local privilege escalation (LPE) vulnerability has been identified in Phish Alert Button for Outlook (PAB), specifically within its configuration management functionalities. This vulnerability allows a regular user to modify the application's configuration file to redirect update checks to an arbitrary server, which can then be exploited in conjunction with CVE-2024-29209 to execute arbitrary code with elevated privileges. The issue stems from improper permission settings on the application's configuration file, which is stored in a common directory accessible to all users. This file includes critical parameters, such as the update server URL. By default, the application does not enforce adequate access controls on this file, allowing non-privileged users to modify it without administrative consent. An attacker with regular user access can alter the update server URL specified in the configuration file to point to a malicious server. When the application performs its next update c…

A medium severity vulnerability has been identified in the update mechanism of the Phish Alert Button for Outlook, which could allow an attacker to remotely execute arbitrary code on the host machine. The vulnerability arises from the application's failure to securely verify the authenticity and integrity of the update server. The application periodically checks for updates by querying a specific URL. However, this process does not enforce strict SSL/TLS verification, nor does it validate the digital signature of the received update files. An attacker with the capability to perform DNS spoofing can exploit this weakness. By manipulating DNS responses, the attacker can redirect the application's update requests to a malicious server under their control. Once the application queries the spoofed update URL, the malicious server can respond with a crafted update package. Since the application fails to properly verify the authenticity of the update file, it will accept and execute the pa…
