A flaw was found in Erlang/OTP inets httpd. An unauthenticated remote attacker can exploit this vulnerability by sending a malformed chunked HTTP request. Specifically, if the chunk-size line is not a hexadecimal number and arrives separately from the headers, the server worker handling the request will not be released. Repeated exploitation can exhaust all available workers, leading to a denial of service (DoS) for legitimate clients.

Threats
Impact Important

A flaw was found in eldap, a component of Erlang/OTP. A malicious or compromised Lightweight Directory Access Protocol (LDAP) server could exploit this vulnerability by returning a referral Uniform Resource Locator (URL) with an excessively long port number. This unbounded port component is then processed by the eldap:parse_port/2 function, leading to a significant increase in processing time due to arbitrary-precision arithmetic. This can degrade the availability of the affected system, resulting in a Denial of Service (DoS).

Threats
Impact Moderate

A flaw was found in the `inets` httpd server, part of Erlang/OTP. The server incorrectly processes HTTP requests that contain both `Transfer-Encoding: chunked` and `Content-Length` headers, failing to reject them or close the connection as required by RFC 9112 §6.1. When `inets` is deployed behind a reverse proxy that prioritizes the `Content-Length` header, a remote attacker can exploit this discrepancy to smuggle malicious requests. This can lead to bypassing access controls, poisoning responses for other users, and circumventing authentication mechanisms enforced by the proxy.

CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling')

Threats
Impact Important

A flaw was found in the inets application HTTP server httpd. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted chunked request that fails to enforce a configured body-size limit. This can lead to memory exhaustion, causing a Denial of Service (DoS) on the affected system.

Threats
Impact Important

A flaw was found in the `mod_auth` module of OTP's inets httpd server. When configured with multiple directory configuration blocks and using `dets` or `mnesia` authentication backends, the module incorrectly collapses all directory blocks into a single shared user/group namespace. This allows a user authenticated for one protected directory to gain unauthorized access to other protected directories on the same server instance, leading to an authentication bypass.
