Details

Reliance on IP Address for Authentication vulnerability in Erlang/OTP ssl (inettlsdist module) allows unauthenticated bypass of the distribution-over-TLS LAN allowlist. The inettlsdist:checkip/1 function, which enforces a LAN allowlist for Erlang distribution over TLS, calls inet:sockname/1 instead of inet:peername/1 to obtain the peer's IP address. Because inet:sockname/1 returns the local socket address, both the local IP and the supposed peer IP resolve to the same value, causing the subnet mask comparison to always succeed regardless of the actual remote address. Any holder of a CA-signed TLS certificate can therefore bypass the LAN restriction and gain full Erlang distribution access to the node, including rpc:call/4 and code:loadbinary/3. This vulnerability is associated with program file lib/ssl/src/inettlsdist.erl. This issue affects OTP from OTP 26.0 before 29.0.2, 28.5.0.2 and 27.3.4.13 corresponding to ssl from 11.0 before 11.7.2, 11.6.0.2 and 11.2.12.9.
