Microsoft apps for macOS have been found vulnerable to library injection attacks, enabling malicious actions without user interaction. Researchers at Cisco Talos identified that these apps, including Outlook, Teams, PowerPoint, and more, disable library validation, allowing attackers to gain unauthorized access. Despite being alerted, Microsoft has categorized the issue as low-severity and has yet to issue a fix.
Based on the meeting notes, the key takeaways are:
1. Widely used Microsoft apps for macOS are vulnerable to library injection attacks that allow adversaries to bypass macOS’s security controls and execute malicious actions without user knowledge or interaction.
2. Eight major Microsoft apps for macOS, including Outlook, Teams, PowerPoint, OneNote, Excel, and Word, were found to be vulnerable to library injection attacks by researchers from Cisco Talos.
3. Microsoft has been characterized the issue as low-severity and has decided not to issue a fix, which has raised concerns about the potential risks of downplaying these vulnerabilities.
4. The decision by Microsoft to disable library validation in these apps has been criticized for undermining the security and privacy protections provided by Apple’s TCC framework.
5. Soroko recommends that organizations review and tighten app permissions and implement monitoring for unusual activity to mitigate the risks associated with these vulnerabilities.
