Detection & IOCsextracted from sources · hover to see the quote
- →Detect specially crafted PPTP protocol messages sent to a Routing and Remote Access Service (RRAS) server, which may indicate exploitation attempts targeting CVE-2022-23270. ↗
- →Monitor for race condition exploitation patterns in PPTP/RRAS traffic; exploitation requires winning a race condition (CVSS AC:H), so repeated rapid connection attempts to RRAS may be indicative. ↗
- →Exploitation likelihood is rated 'More Likely' for both latest and older software releases per Microsoft's exploit assessment; prioritize detection on RRAS/PPTP-exposed systems. ↗
- ·The vulnerability is unauthenticated — no credentials are required for an attacker to send the malicious PPTP protocol message, meaning perimeter controls blocking unauthenticated PPTP (TCP/1723 and GRE) are a critical mitigation layer. ↗
- ·As of the advisory publication, no public exploit or active exploitation had been observed, but Microsoft assessed exploitation as 'More Likely' across all affected software releases. ↗

Windows Point-to-Point Tunneling Protocol Remote Code Execution Vulnerability
FAQ: According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?
Successful exploitation of this vulnerability requires an attacker to win a race condition.
FAQ: How could an attacker exploit this vulnerability?
An unauthenticated attacker could send a specially crafted protocol message to a Routing and Remote Access Service (RRAS) server, which could lead to remote code execution (RCE) on the RAS server machine.

[HIGH] Microsoft Patch Tuesday for May 2022 — Snort rules and prominent vulnerabilities
## Microsoft Patch Tuesday for May 2022 — Snort rules and prominent vulnerabilities
Microsoft returned to its normal monthly patching volume in May, disclosing and fixing 74 vulnerabilities as part of the company’s latest security update. This month’s Patch Tuesday includes seven critical vulnerabilities after Microsoft disclosed more than 140 security issues in April .
The point-to-point tunneling feature in Windows contains two of the most serious vulnerabilities that could allow an attacker to execute remote code on a targeted RAS server machine. While CVE-2022-21972 and CVE-2022-23270 are rated “critical,” Microsoft stated the attack complexity is high since an adversary needs to win a race condition, making it less likely an attacker could exploit these issues.
