Allocation of Resources Without Limits or Throttling vulnerability in Erlang OTP ssh (ssh_sftp modules) allows Excessive Allocation, Resource Leak Exposure. This vulnerability is associated with program files lib/ssh/src/ssh_sftpd.erl.
This issue affects OTP form OTP 17.0 until OTP 28.0.3, OTP 27.3.4.3 and 26.2.5.15 corresponding to ssh from 3.0.1 until 5.3.3, 5.2.11.3 and 5.1.4.12.
A resource exhaustion flaw has been discovered in the Erlang OTP and ssh module. Accessing unverified paths from authenticated SFTP users can lead to excessive CPU and memory usage, potentially affecting system stability.
Меры по смягчению последствий
Users unable to upgrade may disable Erlang SFTP access to mitigate the attack vector or limit the number of max_sessions allowed for sshd to increase the complexity of the attack.
