Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2019-10746)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation within the Configuration (Kibana) component in Oracle Communications Cloud Native Core Network Function Cloud Native Environment. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.
2) Prototype pollution (CVE-ID: CVE-2019-10747)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the "set-value" function fails to validate which Object properties it updates. A remote attacker can modify the prototype of Object using any of the constructor, prototype and "_proto_ payloads", causing the addition or modification of an existing property on all objects, trigger resource exhaustion and perform a denial of service attack.
3) Incorrect Regular Expression (CVE-ID: CVE-2020-7754)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation when processing regular expressions. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
4) Prototype pollution (CVE-ID: CVE-2020-7788)
The vulnerability allows a remote attacker to execute arbitrary code.
The vulnerability exists due to improper input validation when handling INI files. A remote attacker can pass a specially crafted INI file to the application and perform prototype pollution attacks.
5) Use-after-free (CVE-ID: CVE-2020-8265)
The vulnerability allows a remote attacker to perform a DoS attack..
The vulnerability exists due to a use-after-free error in TLSWrap within the TLS implementation. A remote attacker can send specially crafted data to the service and perform a denial of service (DoS) attack.
6) HTTP request smuggling (CVE-ID: CVE-2020-8287)
The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
