Detection & IOCsextracted from sources · hover to see the quote
- →Target service for exploitation is Routing and Remote Access Service (RRAS); monitor for unexpected or malformed inbound PPTP/RAS protocol messages to RRAS servers ↗
- →Exploitation requires winning a race condition (AC:H); look for repeated or high-frequency connection attempts to RRAS/PPTP endpoints as a precursor indicator ↗
- ·Exploit had not been publicly disclosed or observed in the wild at time of advisory publication; exploitation rated 'Less Likely' for both latest and older software releases ↗
- ·Customer action is required; patching RRAS/Windows hosts with the relevant KB updates is necessary to remediate exposure ↗

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.
