Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
EUVDB-ID: #VU11284
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-15715
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass security restrictions on the target system.
The weakness exists on systems that allow uploading of user-specified filenames due to the '<FilesMatch>' expression may not correctly match characters in a filename. A remote attacker can supply a specially crafted filename to potentially bypass security
controls that use the '<FilesMatch>' directive.

EUVDB-ID: #VU26527
Risk: Medium
CVSSv4.0: 1.2 [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:Green]
CVE-ID: CVE-2020-1927
CWE-ID:
CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to redirect victims to arbitrary URL.
The vulnerability exists due to improper sanitization of user-supplied data in some "mod_rewrite" configurations. A remote attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary domain.
Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.
