Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2020-27218)
The vulnerability allows a remote non-authenticated attacker to manipulate or delete data.
The vulnerability exists due to improper input validation within the SC Admin server (Eclipse Jetty) component in Oracle Communications Converged Application Server - Service Controller. A remote non-authenticated attacker can exploit this vulnerability to manipulate or delete data.
2) Path traversal (CVE-ID: CVE-2021-29425)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error within the FileNameUtils.normalize method when processing directory traversal sequences, such as "//../foo", or "\..foo". A remote attacker can send a specially crafted request and verify files availability in the parent folder.
3) Cross-site scripting (CVE-ID: CVE-2020-11022)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in the regex operation in "jQuery.htmlPrefilter". A remote attacker can pass specially crafted data to the application that uses .html()</code>, <code>.append() or similar methods for it and execute arbitrary JavaScript code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
4) Protection mechanism failure (CVE-ID: CVE-2019-10086)
The vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exist due to Beanutils is not using by default the a special BeanIntrospector class in PropertyUtilsBean that was supposed to suppress the ability for an attacker to access the classloader via the class property available on all Java objects. A remote attacker can abuse such application behavior against applications that were developed to rely on this security feature.
5) Prototype polution (CVE-ID: CVE-2020-8203)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data when using _.zipObjectDeep in lodash. A remote attacker can inject and execute arbitrary script code.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
6) Improper Authorization (CVE-ID: CVE-2019-13565)
7) 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.
8) Resource management error (CVE-ID: CVE-2020-17527)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to improper management of internal resources within the application when processing HTTP/2 requests in Apache Tomcat. The web server can re-use an HTTP request header value from the previous stream received on an
HTTP/2 connection for the request associated with the subsequent stream. As a result a remote attacker can obtain sensitive information from another HTTP request.
9) Information disclosure (CVE-ID: CVE-2019-12399)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output within the Apache Kafka Connect REST API tasks endpoint. A remote authenticated user can issue a request to the same Connect cluster to obtain the connector's task configurations and the response will contain the plaintext secret.
10) 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.
11) 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.
12) Buffer overflow (CVE-ID: CVE-2020-8174)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within napi_get_value_string_latin1(), napi_get_value_string_utf8(), or napi_get_value_string_utf16() functions. A remote attacker can create a specially crafted data to the application, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
13) Improper input validation (CVE-ID: CVE-2021-2351)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The vulnerability exists due to improper input validation within the Advanced Networking Option in Oracle Database Server. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.
14) Code Injection (CVE-ID: CVE-2020-5245)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation. A remote authenticated attacker can inject arbitrary Java Expression Language expressions when using the self-validating feature and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
15) Off-by-one (CVE-ID: CVE-2021-23017)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to an off-by-one error within the ngx_resolver_copy() function when processing DNS responses. A remote attacker can trigger an off-by-one error, write a dot character (‘.’, 0x2E) out of bounds in a heap allocated buffer and execute arbitrary code on the system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
The vulnerability can be triggered by a DNS response in reply to a DNS request from nginx when the resolver primitive is configured. A specially crafted packet allows overwriting the least significant byte of next heap chunk metadata with 0x2E.
