EUVDB-ID: #VU33011
Risk: Medium
CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2016-8616
CWE-ID:
CWE-255 - Credentials Management
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to manipulate data.
A flaw was found in curl before version 7.51.0 When re-using a connection, curl was doing case insensitive comparisons of user name and password with the existing connections. This means that if an unused connection with proper credentials exists for a protocol that has connection-scoped credentials, an attacker can cause that connection to be reused if s/he knows the case-insensitive version of the correct password.
MitigationInstall update from vendor's website.
Vulnerable software versionscURL: 7.1 - 7.50.3
