Description
This security bulletin contains information about 10 vulnerabilities.
1) XML External Entity injection (CVE-ID: CVE-2019-10172)
CWE-ID: CWE-611 - Improper Restriction of XML External Entity Reference ('XXE')
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied XML input. A remote attacker can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.
Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
2) XML External Entity injection (CVE-ID: CVE-2016-3720)
CWE-ID: CWE-611 - Improper Restriction of XML External Entity Reference ('XXE')
CVSSv4: 9.3 [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]
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied XML input within the XmlMapper. A remote attacker can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.
Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
3) Input validation error (CVE-ID: CVE-2019-10202)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to incorrect implementation of patch for Codehaus 1.9.x against insufficient data deserialization present in FasterXML jackson-databind. A remote attacker can bypass implemented protection measures and exploit known deserialization vulnerabilities in jackson-databind package.4) Deserialization of untrusted data (CVE-ID: CVE-2017-17485)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: 9.3 [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]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists in the FasterXML jackson-databind library due to improper validation of user-input handled by the readValue method of the ObjectMapper object. A remote attacker can send malicious input to the vulnerable method of a web application that uses the Spring library in the application's classpath and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
5) Deserialization of untrusted data (CVE-ID: CVE-2017-7525)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: 9.3 [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]
The 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.
6) Remote code execution (CVE-ID: CVE-2017-15095)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 9.3 [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]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists in the jackson-databind development library due to improper implementation of blacklists for input handled by the ObjectMapper object readValue method. A remote unauthenticated attacker can send a malicious input and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Deserialization of untrusted data (CVE-ID: CVE-2018-5968)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: 9.3 [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]
The vulnerability allows a remote attacker to execute arbitrary code.
The weakness exists due to deserialization flaw. A remote attacker can supply specially crafted input, execute arbitrary code and bypass a blacklist on the target system.
Successful exploitation of the vulnerability may result in system compromise.
8) Deserialization of untrusted data (CVE-ID: CVE-2018-7489)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: 9.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote unauthenticated attacker to bypass security restrictions and execute arbitrary code on the target system.
The weakness exists in the readValue method due to improper validation of user-input. A remote attacker can send malicious JSON input, bypass security restrictions and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
9) Input validation error (CVE-ID: CVE-2018-1000873)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can trick the victim into deserializing of crafted input with specifically very large values in the nanoseconds field of a time value and cause the service to crash.
10) Information disclosure (CVE-ID: CVE-2019-12086)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a polymorphic typing issue when Default Typing is enabled for an externally exposed JSON endpoint and the service has the mysql-connector-java jar in the classpath. A remote attacker can send a specially crafted JSON message and read arbitrary local files on the server due to the missing "com.mysql.cj.jdbc.admin.MiniAdmin" validation.
