Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU48792
Risk: Low
CVSSv3.1: 3.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-17521
CWE-ID:
CWE-276 - Incorrect Default Permissions
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to incorrect default permissions for temporary files and folders that are set by the application. A local user with access to the system can view contents of files and directories or modify them.
MitigationInstall update from vendor's website.
Vulnerable software versionsOracle Communications BRM - Elastic Charging Engine: 11.3.0.9.0 - 12.0.0.3.0

Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
The attacker would have to login to the system and perform certain actions in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
EUVDB-ID: #VU27513
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-11612
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources within ZlibDecoders in Netty while decoding a ZlibEncoded byte stream. A remote attacker can trigger resource exhaustion by passing an overly large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.

EUVDB-ID: #VU52562
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-21345
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 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.
