Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2020-8554)
The vulnerability allows a remote authenticated user to read and manipulate data.
The vulnerability exists due to improper input validation within the UDR (Kubernetes API) component in Oracle Communications Cloud Native Core Unified Data Repository. A remote authenticated user can exploit this vulnerability to read and manipulate data.
2) Improper input validation (CVE-ID: CVE-2020-29582)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the Signaling (Calico) component in Oracle Communications Cloud Native Core Network Slice Selection Function. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
3) Improper access control (CVE-ID: CVE-2021-34429)
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper input validation when processing certain characters in URI. A remote attacker can send a specially crafted HTTP request with encoded characters in URI, bypass implemented security restrictions and access content of the WEB-INF directory.
4) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2021-33037)
The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests, related to processing of transfer encoding headers. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
5) Input validation error (CVE-ID: CVE-2020-13956)
The vulnerability allows a remote attacker to compromise the affected application.
The vulnerability exists due to insufficient validation of user-supplied input in Apache HttpClient. A remote attacker can pass request URIs to the library as java.net.URI object and force the application to pick the wrong target host for request execution.
6) Infinite loop (CVE-ID: CVE-2020-27618)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within iconv implementation when processing multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, IBM1399 encodings. A remote attacker can pass specially crafted data to the application, consume all available system resources and cause denial of service conditions.
7) Observable discrepancy (CVE-ID: CVE-2021-33880)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to observable timing discrepancy on server when HTTP Basic authentication is enabled with basic_auth_protocol_factory(credentials=...). A remote attacker can guess passwords via timing attack.
8) Improper input validation (CVE-ID: CVE-2020-14340)
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 UDR (XNIO) component in Oracle Communications Cloud Native Core Unified Data Repository. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.
9) Resource exhaustion (CVE-ID: CVE-2021-36090)
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 when processing ZIP archives. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
10) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2021-22118)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to application does not properly impose security restrictions in the WebFlux application, which leads to security restrictions bypass and privilege escalation.
