Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2020-13954)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the Supplier Direct Fulfillment (Apache CXF) component in Oracle Retail Order Broker Cloud Service. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
2) Use-after-free (CVE-ID: CVE-2020-13871)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in resetAccumulator() function in select.c. A remote attacker can pass specially crafted data to the application, trigger a use-after-free error and crash the service or execute arbitrary code on the target system
3) Deserialization of Untrusted Data (CVE-ID: CVE-2020-24750)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
FasterXML jackson-databind 2.x before 2.9.10.6 mishandles the interaction between serialization gadgets and typing, related to com.pastdev.httpcomponents.configuration.JndiConfiguration. A remote attacker can execute arbitrary code on the target system.
4) Comparison using wrong factors (CVE-ID: CVE-2020-28052)
The vulnerability allows a remote attacker to brute-force password hashes.
The vulnerability exists due to comparison error in OpenBSDBCrypt.checkPassword() function in core/src/main/java/org/bouncycastle/crypto/generators/OpenBSDBCrypt.java when matching passwords with hashes. A remote attacker can pass an incorrect password that will be accepted as a valid one by the library, bypass authentication process and gain unauthorized access to the application that uses vulnerable version of Bouncy Castle.
5) Resource exhaustion (CVE-ID: CVE-2020-11612)
The 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.
6) XML External Entity injection (CVE-ID: CVE-2019-0228)
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 XFDF file 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.
