Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Deserialization of Untrusted Data
EUVDB-ID: #VU68635
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-2022-42003
CWE-ID:
CWE-502 - Deserialization of Untrusted Data
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insecure input validation when processing serialized data when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled. A remote attacker can pass specially crafted data to the application and cause a denial of service condition on the target system.
MitigationInstall update from vendor's website.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Input validation error
EUVDB-ID: #VU69293
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-3171
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input containing multiple instances of non-repeated embedded messages with repeated or unknown fields. A remote attacker can cause objects to be converted back-n-forth between mutable and immutable forms, resulting in potentially long garbage collection pauses.

3) Out-of-bounds write
EUVDB-ID: #VU64075
Risk: Low
CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-1304
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input. A local attacker can use a specially crafted filesystem, trigger out-of-bounds write and execute arbitrary code on the target system.
MitigationInstall update from vendor's website.
Vulnerable software versionsOracle Communications Cloud Native Core Network Exposure Function: 22.3.1 - 22.4.0
External linkshttp://www.oracle.com/security-alerts/cpujan2023.html?952634
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.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
4) Improper Authorization
EUVDB-ID: #VU68866
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-2022-31692
CWE-ID:
