Outlook

Remote code execution in Microsoft Office Outlook stems from an integer overflow or wraparound condition (CWE-190) that allows an unauthenticated network attacker to execute arbitrary code on a victim's system, achieving full confidentiality, integrity, and availability compromise. The CVSS 3.1 score of 8.8 (High) with vector AV:N/AC:L/PR:N/UI:R reflects low attack complexity and no authentication requirement, though exploitation is gated by a user interaction step. No public exploit code and no CISA KEV listing have been identified at time of analysis, but the attack profile is consistent with phishing-delivered malicious email or attachment campaigns targeting Outlook users.

Insufficiently protected credentials in Microsoft Office Outlook expose authentication material over network connections, enabling unauthenticated network-positioned attackers to perform spoofing attacks contingent on victim user interaction. The flaw affects Outlook 2016, Office 2019, Office LTSC 2021, Office LTSC 2024, and Microsoft 365 Apps for Enterprise - collectively spanning nearly the entire current Outlook product line. Microsoft has released a patch; no public exploit or active exploitation (CISA KEV) has been identified at time of analysis.

SpotOutlook 1.2.6 contains a denial of service vulnerability in the registration name input field that allows attackers to crash the application. Attackers can overwrite the buffer by pasting 1000 'A' characters into the 'Name' field, causing the application to become unresponsive. [CVSS 7.5 HIGH]

Microsoft Outlook's unsafe deserialization of untrusted data enables remote attackers to spoof messages and identities without authentication over the network. This vulnerability affects Outlook, Word, and Microsoft 365 Apps, allowing attackers to impersonate legitimate senders and deceive users. No patch is currently available, making this a high-risk threat requiring immediate defensive measures.

Information disclosure in Microsoft Outlook, SharePoint Server, Office, and 365 Apps enables remote attackers to conduct email spoofing attacks without authentication or user interaction. The vulnerability affects multiple Microsoft collaboration products and could allow threat actors to impersonate legitimate senders to compromise organizational security. No patch is currently available for this high-severity issue.
