CVSSv3: 8.5 [CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C] [PCI]
CVE-ID: CVE-2020-28949
CWE-ID:
CWE-20 - Improper Input Validation
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to improper sanitization of the user-supplied input when processing URI handlers in filenames. A remote attacker can pass the "file://" string in the filename and overwrite arbitrary files on the system.
Install updates from vendor's website.
To mitigate this issue, prevent untrusted users from uploading .tar, .tar.gz, .bz2 or .tlz files.

Risk: High
CVSSv3: 8.5 [CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C] [PCI]
CVE-ID: CVE-2020-28948
CWE-ID:
CWE-502 - Deserialization of Untrusted Data
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data, related to case sensitivity issues (e.g. "phar:" protocol is blocked, however "PHAR:" is not). A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationInstall updates from vendor's website.
To mitigate this issue, prevent untrusted users from uploading .tar, .tar.gz, .bz2 or .tlz files.
