DescriptionCVE.org

The inets application HTTP server httpd fails to enforce a configured body-size limit on chunked request.

This issue affects OTP from OTP 17.0 before OTP 27.3.4.17, from OTP 28.0 before OTP 28.5.0.6, and from OTP 29.0 before OTP 29.0.6, corresponding to inets from 5.10 before 9.3.2.7, from 9.4 before 9.6.2.3, and from 9.7 before 9.7.2. Whether OTP before OTP 17.0, corresponding to inets before 5.10, is affected is unknown.

AnalysisAI

Erlang/OTP's inets HTTP server (httpd) fails to enforce an administrator-configured request body-size limit when processing chunked transfer-encoded requests, enabling unauthenticated remote attackers to exhaust server memory and cause denial of service. Affected OTP branches span 17.x through 27.3.4.16, 28.x through 28.5.0.5, and 29.x through 29.0.5, covering inets versions 5.10 through 9.7.1. …

Vulnerability AssessmentAI

Exploitation The target must be running Erlang/OTP's inets httpd specifically (not Cowboy, Ranch, Phoenix, or any other HTTP server) on an affected OTP version. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The provided CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VA:H) scores 8.7, reflecting a remotely exploitable, unauthenticated, low-complexity attack with high availability impact and no confidentiality or integrity consequences. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade to OTP 27.3.4.17 (inets 9.3.2.7), OTP 28.5.0.6 (inets 9.6.2.3), or OTP 29.0.6 (inets 9.7.2) depending on the OTP branch in use. … Detailed patch versions, workarounds, and compensating controls in full report.
Sign in to read full assessment

Recommended ActionAI

Within 24 hours, identify all Erlang/OTP deployments running versions 17.x through 27.3.4.16, 28.x through 28.5.0.5, or 29.x through 29.0.5; prioritize systems with external network exposure. …
