Published: 09 August 2022
Summary
CVE-2022-35769 is a high-severity Uncontrolled Resource Consumption (CWE-400) vulnerability in Microsoft Windows 10. Its CVSS base score is 7.5 (High).
Operationally, ranked in the top 4.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Windows Point-to-Point Protocol (PPP) contains a denial-of-service vulnerability tracked as CVE-2022-35769. The flaw affects the PPP implementation in Windows and is characterized by CWE-400, allowing an unauthenticated remote attacker to trigger excessive resource consumption that leads to high availability impact without affecting confidentiality or integrity.
An attacker can exploit the issue over the network with low attack complexity and no required privileges or user interaction. Successful exploitation results in a denial-of-service condition that disrupts PPP-based connectivity while leaving other system functions unaffected.
Microsoft has published remediation guidance for CVE-2022-35769 in its security update guide. The EPSS score for the vulnerability has remained flat at a peak of 0.2039 since disclosure, indicating no material increase in observed exploitation interest.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Limiting concurrent sessions directly prevents uncontrolled resource consumption by capping the number of active sessions per user or account.
Analysis identifies uncontrolled resource consumption indicative of denial-of-service or abuse attempts.
Contingency plan testing includes resource exhaustion scenarios to verify recovery, making it harder for attackers to sustain exploits that cause uncontrolled consumption.
Updated contingency plans include current procedures to detect, contain, and recover from resource exhaustion, limiting an attacker's ability to sustain impact from uncontrolled consumption.
Alternate site allows resumption of operations if resource exhaustion at the primary site is exploited to cause unavailability.
Alternate telecommunications services enable resumption of essential functions when primary services become unavailable due to uncontrolled resource consumption.
The team can analyze and respond to resource exhaustion incidents, reducing the impact of attacks that exploit uncontrolled consumption weaknesses.
Timely maintenance support and spare parts enable rapid recovery from failures induced by uncontrolled resource consumption, shortening the impact window of denial-of-service attacks.
