December Microsoft Patch Tuesday

December Microsoft Patch Tuesday. 89 CVEs, of which 18 were added since November MSPT. 1 vulnerability with signs of exploitation in the wild:

🔻 EoP – Windows Common Log File System Driver (CVE-2024-49138). There are no details about this vulnerability yet.

Strictly speaking, there was another vulnerability that was exploited in the wild: EoP – Microsoft Partner Network (CVE-2024-49035). But this is an already fixed vulnerability in the Microsoft website and I’m not even sure that it was worth creating a CVE. 🤔

For the remaining vulnerabilities, there are no signs of exploitation in the wild, nor exploits (even private ones).

I can highlight:

🔹 RCE – Windows LDAP (CVE-2024-49112, CVE-2024-49127)
🔹 RCE – Windows LSASS (CVE-2024-49126)
🔹 RCE – Windows Remote Desktop Services (CVE-2024-49106 и ещё 8 CVE)
🔹 RCE – Microsoft MSMQ (CVE-2024-49122, CVE-2024-49118)
🔹 RCE – Microsoft SharePoint (CVE-2024-49070)

About Elevation of Privilege - Windows Task Scheduler (CVE-2024-49039) vulnerability

About Elevation of Privilege – Windows Task Scheduler (CVE-2024-49039) vulnerability. It was released on November Microsoft Patch Tuesday and showed signs of exploitation in the wild right away. To exploit the vulnerability, an authenticated attacker runs a specially crafted application on the target system. The attack can be performed from an AppContainer restricted environment. Using this vulnerability, an attacker can elevate their privileges to Medium Integrity level and gain the ability to execute RPC functions that are restricted to privileged accounts only.

ESET reports that the vulnerability allowed the RomCom attackers to execute malicious code outside the Firefox sandbox and then launch hidden PowerShell processes to download and run malware from C&C servers.

👾 There is a backdoor code on GitHub that exploits this vulnerability.

About Elevation of Privilege - needrestart (CVE-2024-48990) vulnerability

About Elevation of Privilege – needrestart (CVE-2024-48990) vulnerability. On November 19, Qualys released a security bulletin about five privilege escalation vulnerabilities in the needrestart utility (CVE-2024-48990, CVE-2024-48991, CVE-2024-48992, CVE-2024-10224, and CVE-2024-11003) used in Ubuntu Server, starting with version 21.04.

The needrestart utility runs automatically after APT operations (installing, updating, or removing packages). It checks if a reboot is required, thus ensuring that services use updated libraries without unnecessary downtime.

All 5 vulnerabilities make it possible for a regular user to become root. Qualys has private exploits for each. There is currently a publicly available exploit only for one vulnerability related to the PYTHONPATH environment variable.⚡️ It is available on Github since November 20th.

Update needrestart to version 3.8 or disable “interpreter scanning” in needrestart.conf.

About Elevation of Privilege - PAN-OS (CVE-2024-9474) vulnerability

About Elevation of Privilege – PAN-OS (CVE-2024-9474) vulnerability. An attacker with PAN-OS administrator access to the management web interface can perform actions on the Palo Alto device with root privileges. Linux commands can be injected via unvalidated input in script.

The need for authentication and admin access could limit this vulnerability’s impact, but here we have the previous vulnerability Authentication Bypass – PAN-OS (CVE-2024-0012). 😏 Exploitation of this vulnerability chain was noted by Palo Alto on November 17. After November 19, when the watchTowr Labs article was published and exploits appeared, mass attacks began.

On November 21, Shadowserver reported that ~2000 hosts were compromised, mostly in the US and India. According to Wiz, attackers deployed web shells, Sliver implants and cryptominers.

About Authentication Bypass - PAN-OS (CVE-2024-0012) vulnerability

About Authentication Bypass – PAN-OS (CVE-2024-0012) vulnerability. An unauthenticated attacker with network access to the Palo Alto device web management interface could gain PAN-OS administrator privileges to perform administrative actions, tamper with the configuration, or exploit other authenticated vulnerabilities. Firewalls of the PA, VM, CN series and the Panorama management platform are vulnerable. The vendor recommends restricting access to the management web interface to trusted internal IP addresses only.

🔻 On November 8, a Palo Alto bulletin was released
🔻 On November 15, signs of attacks were noticed, labeled as “Operation Lunar Peek”
🔻 On November 18, the vulnerability was added to the CISA KEV
🔻 On November 19, watchTowr Labs released a post with technical details (“supply the off value to the X-PAN-AUTHCHECK HTTP request header, and the server helpfully turns off authentication”) 😏 and exploits soon appeared on GitHub
