Name of the Vulnerable Software and Affected Versions Phish Alert Button (PAB) for Outlook versions 1.10.0 through 1.10.11 Second Chance Client versions 2.0.0 through 2.0.9 PIQ Client versions 1.0.0 through 1.0.15

Description 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, but 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. Successful exploitation of this vulnerability allows an attacker to execute code with elevated privileges, potentially leading to data theft, installation of further malware, or other malicious activities on the host system.

Recommendations For Phish Alert Button (PAB) for Outlook versions 1.10.0 through 1.10.11, apply the latest updates provided by KnowBe4, which addresses this vulnerability by implementing proper SSL/TLS checks of the update server. For Second Chance Client versions 2.0.0 through 2.0.9, apply the latest updates provided by KnowBe4, which addresses this vulnerability by implementing proper SSL/TLS checks of the update server. For PIQ Client versions 1.0.0 through 1.0.15, apply the latest updates provided by KnowBe4, which addresses this vulnerability by implementing proper SSL/TLS checks of the update server. As a temporary workaround, consider using secure corporate networks or VPN services to secure network communications, which can help mitigate the risk of DNS spoofing. Ensure DNS settings are secure to prevent DNS spoofing attacks.
