Description
This security bulletin contains information about 2 vulnerabilities.
1) Open redirect (CVE-ID: CVE-2018-19790)
CWE-ID: CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote unauthenticated attacker to redirect the target user to external websites.
The weakness exists due to improper sanitization of user-supplied data. A remote attacker can use backslashes in the `_failure_path` input field of login forms, work around the redirection target restrictions and effectively redirect the user to any domain after login.
2) Improper input validation (CVE-ID: CVE-2018-19789)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to an error when using the scalar type hint `string` in a setter method (e.g. `setName(string $name)`) of a class that's the `data_class` of a form A remote unauthenticated attacker can submit a file upload to the corresponding field instead of a normal text input, call `UploadedFile::__toString()` which will then return and disclose the path of the uploaded file. If combined with a local file inclusion issue in certain circumstances a remote attacker can execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
