Patch Tuesday: Remote Code Execution Flaw in Microsoft Message Queuing

The Windows vulnerability carries a CVSS severity score of 9.8/10 and can be exploited by via specially crafted malicious MSMQ packets.

Microsoft Zero-Days

Software giant Microsoft on Tuesday called on Windows administrators to pay urgent attention to patches for a critical remote code execution vulnerability in the Microsoft Message Queuing (MSMQ) component.

The vulnerability, tagged as CVE-2024-30080, carries a CVSS severity score of 9.8/10 and can be exploited by an attacker sending specially crafted malicious MSMQ packets to a MSMQ server.

“This could result in remote code execution on the server side,” Redmond’s security response team warned in an advisory.

Microsoft said the Windows message queuing service needs to be enabled for a system to be exploitable by this vulnerability and urged customers to check to see if there is a service running named Message Queuing and TCP port 1801 is listening on the machine.

The MSMQ flaw headlines another hefty Patch Tuesday that covers at least 51 security defects across a range of Windows OS, components and services.

The company documented multiple code execution issues in the Microsoft Office productivity suite, remotely exploitable bugs in the Windows Link Layer Topology Discovery Protocol and Windows Event Trace Log File Parsing,  

Security experts are also calling attention to CVE-2024-30078, a Windows WiFi driver remote code execution vulnerability with a CVSS severity score of 8.8/10.

“Exploiting this vulnerability requires an attacker to be within proximity of the target system to send and receive radio transmissions. An unauthenticated attacker could send a malicious networking packet to an adjacent system that is employing a Wi-Fi networking adapter, which could enable remote code execution,” Microsoft warned.

Separately, software maker Adobe warned of the risk of code execution attacks on Windows and macOS platforms via security flaws in the Adobe Photoshop, Adobe After Effects and Adobe Illustrator products.

Adobe said it was not aware of any exploits in the wild for any of the issues addressed this month.
