| CVE-2024-29209 | 2024-05-07 | N/A | 6.0 MEDIUM | ||
| 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 package, leading to arbitrary code execution on the host machine. Impact: 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. Affected Products: Phish Alert Button (PAB) for Outlook versions 1.10.0-1.10.11 Second Chance Client versions 2.0.0-2.0.9 PIQ Client versions 1.0.0-1.0.15 Remediation: Automated updates will be pushed to address this issue. Users of affected versions should verify the latest version is applied and, if not, apply the latest updates provided by KnowBe4, which addresses this vulnerability by implementing proper SSL/TLS checks of the update server. It is also recommended to ensure DNS settings are secure to prevent DNS spoofing attacks. Workarounds: Use secure corporate networks or VPN services to secure network communications, which can help mitigate the risk of DNS spoofing. Credits: This vulnerability was discovered by Ceri Coburn at Pen Test Partners, who reported it responsibly to the vendor. | |||||
| CVE-2024-29210 | 2024-05-07 | N/A | 2.8 LOW | ||
| 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 check, it will contact the attacker-controlled server. If the system is also vulnerable to CVE-2024-29209, the attacker can deliver a malicious update package that, when executed, grants them elevated privileges. Impact: This vulnerability can lead to a regular user executing code with administrative privileges. This can result in unauthorized access to sensitive data, installation of additional malware, and a full takeover of the affected system. Affected Products: Phish Alert Button (PAB) for Outlook versions 1.10.0-1.10.11 Second Chance Client versions 2.0.0-2.0.9 PIQ Client versions 1.0.0-1.0.15 Remediation: KnowBe4 has released a patch that corrects the permission settings on the configuration file to prevent unauthorized modifications. Automated updates will be pushed to address this issue. Users of affected versions should verify the latest version is applied and, if not, apply the latest updates provided by KnowBe4. Workarounds: Manually set the correct permissions on the configuration file to restrict write access to administrators only.

| CVE-2024-20677 | 1 Microsoft | 3 365 Apps, Office, Office Long Term Servicing Channel | 2024-04-11 | N/A | 7.8 HIGH |
| A security vulnerability exists in FBX that could lead to remote code execution. To mitigate this vulnerability, the ability to insert FBX files has been disabled in Word, Excel, PowerPoint and Outlook for Windows and Mac. Versions of Office that had this feature enabled will no longer have access to it. This includes Office 2019, Office 2021, Office LTSC for Mac 2021, and Microsoft 365. As of February 13, 2024, the ability to insert FBX files has also been disabled in 3D Viewer. 3D models in Office documents that were previously inserted from a FBX file will continue to work as expected unless the Link to File option was chosen at insert time. This change is effective as of the January 9, 2024 security update. | |||||
| CVE-2024-1187 | 1 Munsoft | 1 Easy Outlook Express Recovery | 2024-04-11 | 1.7 LOW | 5.5 MEDIUM |
| A vulnerability, which was classified as problematic, has been found in Munsoft Easy Outlook Express Recovery 2.0. This issue affects some unknown processing of the component Registration Key Handler. The manipulation leads to denial of service. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. The identifier VDB-252677 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. | |||||
| CVE-2002-1777 | 1 Symantec | 1 Norton Antivirus | 2024-04-11 | 7.5 HIGH | N/A |
| NOTE: this issue has been disputed by the vendor. Symantec Norton AntiVirus (NAV) 2002 allows remote attackers to bypass e-mail scanning via a filename in the Content-Type field with an excluded extension such as .nch or .dbx, but a malicious extension in the Content-Disposition field, which is used by Outlook to obtain the file name. NOTE: the vendor has disputed this issue, acknowledging that the initial scan is bypassed, but Norton AntiVirus or the Office plug-in would detect the virus before it is executed | |||||

| CVE-2020-1493 | 1 Microsoft | 3 365 Apps, Office, Outlook | 2024-01-19 | 4.3 MEDIUM | 5.5 MEDIUM |
| An information disclosure vulnerability exists when attaching files to Outlook messages. This vulnerability could potentially allow users to share attached files such that they are accessible by anonymous users where they should be restricted to specific users. To exploit this vulnerability, an attacker would have to attach a file as a link to an email. The email could then be shared with individuals that should not have access to the files, ignoring the default organizational setting. The security update addresses the vulnerability by correcting how Outlook handles file attachment links. | |||||
| CVE-2020-1483 | 1 Microsoft | 3 365 Apps, Office, Outlook | 2024-01-19 | 9.3 HIGH | 5.0 MEDIUM |
| A remote code execution vulnerability exists in Microsoft Outlook when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Outlook software. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file. Note that where severity is indicated as Critical in the Affected Products table, the Preview Pane is an attack vector. The security update addresses the vulnerability by correcting how Outlook handles objects in memory. | |||||
