Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Deserialization of Untrusted Data
EUVDB-ID: #VU53241
Risk: High
CVSSv3.1: 8.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-27475
CWE-ID:
CWE-502 - Deserialization of Untrusted Data
Exploit availability: No
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. A remote attacker can trick a victim to open a specially crafted serialized object and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

2) Path traversal
EUVDB-ID: #VU53242
Risk: Medium
CVSSv3.1: 5.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-27471
CWE-ID:
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences. A remote attacker can send a specially crafted HTTP request and overwrite arbitrary files on the system.

3) Input validation error
EUVDB-ID: #VU53243
Risk: Medium
CVSSv3.1: 6.2 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-27473
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to escalate privileges on the system.
The vulnerability exists due to the affected software does not sanitize paths specified within the .ccwarc archive file during extraction. A remote attacker can gain elevated privileges on the target system.
