Vulnerability CVE-2021-39172
Published: 2021-08-27 Modified: 2021-08-28
| Description: |
Cachet is an open source status page system. Prior to version 2.5.1, authenticated users, regardless of their privileges (User or Admin), can exploit a new line injection in the configuration edition feature (e.g. mail settings) and gain arbitrary code execution on the server. This issue was addressed in version 2.5.1 by improving `UpdateConfigCommandHandler` and preventing the use of new lines characters in new configuration values. As a workaround, only allow trusted source IP addresses to access to the administration dashboard. |
Type:
CWE-93 (Improper Neutralization of CRLF Sequences ('CRLF Injection'))
