Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Deserialization of untrusted data
EUVDB-ID: #VU9128
Risk: High
CVSSv4.0: 8.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]
CVE-ID: CVE-2017-7525
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 weakness exists due to a deserialization flaw in the jackson-databind component. A remote attacker can send a specially crafted input to the readValue method of the ObjectMapper and execute arbitrary code with privileges of the target service.
Successful exploitation of the vulnerability may result in system compromise.
Install 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. However, proof of concept for this vulnerability is available.
2) Information disclosure
EUVDB-ID: #VU9129
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2014-9970
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to gain access to potentially sensitive information.
The weakness exists due to a flaw in the Jasypt component. A local attacker can conduct a timing attack on password hash comparison and obtain passwords on the target system.

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.
3) Privilege escalation
EUVDB-ID: #VU9130
Risk: Low
CVSSv4.0: 7.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:U/U:Clear]
CVE-ID: CVE-2017-7536
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to the security manager's reflective permissions are granted to Hibernate Validator. A local attacker can allow the calling code to access private members without the permission, validate an invalid instance, access the private member value via ConstraintViolation#getInvalidValue() and gain execute arbitrary code with elevated privileges.
