Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Security restrictions bypass
EUVDB-ID: #VU60079
Risk: Low
CVSSv3.1: 6.1 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-23181
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a time of check, time of use flaw when configured to persist sessions using the FileStore. A local user can perform certain actions which lead to security restrictions bypass and privilege escalation (code execution with Tomcat process privileges).
MitigationInstall update from vendor's website.

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.
2) Deserialization of Untrusted Data
EUVDB-ID: #VU28158
Risk: High
CVSSv3.1: 7.3 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2020-9484
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 in uploaded files names. A remote attacker can pass specially crafted file name to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that the server is configured to use PersistenceManager with a FileStore and the attacker knows relative file path from storage location.
