Detection & IOCsextracted from sources · hover to see the quote
- →Detect path traversal attempts via malicious tar file uploads sent to the Defender for IoT sensor update endpoint, particularly unsigned update packages. ↗
- →Monitor for unexpected file overwrites on Defender for IoT sensor hosts, which may indicate successful exploitation of the path traversal vulnerability. ↗
- →Alert on low-privileged authenticated users initiating the update process on Defender for IoT sensors, especially if followed by unsigned package delivery. ↗
- ·Exploitation requires the attacker to be authenticated with at least low-level privileges (sufficient to initiate the update process) on the Defender for IoT sensor — unauthenticated exploitation is not possible for this CVE. ↗
- ·Patched version is 24.1.3 or above; sensors running older versions remain vulnerable. ↗
- ·As of the advisory publication, the vulnerability had not been publicly exploited in the wild (Exploited: No, Publicly Disclosed: No). ↗

FAQ: According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability?
Successful exploitation of this vulnerability requires the attacker to be able to send a malicious update package to the Defender for IoT sensor over the network. To do this, the attacker would first need to authenticate themselves and gain the necessary permissions to initiate the update process.
FAQ: How could an attacker exploit this vulnerability?
Successful exploitation of this path traversal vulnerability would require an attacker to have user credentials on the targeted machine and then send a tar file to the Defender for IoT sensor. After the extraction process completed, the attacker could then send unsig

## April’s Patch Tuesday includes 150 vulnerabilities, 60 which could lead to remote code execution
In one of the largest Patch Tuesdays in years, Microsoft disclosed 150 vulnerabilities across its software and product portfolio this week, including more than 60 that could lead to remote code execution.
Though April’s monthly security update from Microsoft is the largest since at least the start of 2023, only three of the issues disclosed are considered “critical,” all of which are remote code execution vulnerabilities in Microsoft Defender for IoT.
Most of the remainder of the security issues are considered “important,” and only two are “moderate” severity.
The three critical vulnerabilities — CVE-2024-21322 , CVE-2024-21323 and CVE-2024-29053 — are all remote code execution vulnerabi
