PatchTheCVECVE-2017-14623: In the ldap.v2 (aka go-ldap) package through 2.5.0 for Go, an attacker may be able to login with an empty pass
CVE-2017-14623 is a high-severity flaw (CVSS 8.1) affecting ldap. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
In the ldap.v2 (aka go-ldap) package through 2.5.0 for Go, an attacker may be able to login with an empty password. This issue affects an application using this package if these conditions are met: (1) it relies only on the return error of the Bind function call to determine whether a user is authorized (i.e., a nil return value is interpreted as successful authorization) and (2) it is used with an LDAP server allowing unauthenticated bind.
Why this priority
- High severity
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
