Description

This security bulletin contains information about 9 secuirty vulnerabilities.


1) Improper input validation (CVE-ID: CVE-2021-2471)

The vulnerability allows a remote privileged user to read data or crash the application.

The vulnerability exists due to improper input validation within the Connector/J component in MySQL Connectors. A remote privileged user can exploit this vulnerability to read data or crash the application.


2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2021-43797)

The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests when processing control chars present at the beginning / end of the header name. 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.


3) Code Injection (CVE-ID: CVE-2021-44832)

The vulnerability allows a remote user to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation. A remote user with permission to modify the logging configuration file can construct a malicious configuration using a JDBC Appender with a data source referencing a JNDI URI which can execute remote code.


4) Cleartext transmission of sensitive information (CVE-ID: CVE-2021-22946)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to an error, related to incorrect enforcement of the --ssl-reqd option on the command line or CURLOPT_USE_SSL setting set to CURLUSESSL_CONTROL or CURLUSESSL_ALL with libcurl. A remote attacker with control over the IMAP, POP3 or FTP server can send a specially crafted but perfectly legitimate response to the libcurl client and force it silently to continue its operations without TLS encryption and transmit data in clear text over the network.


5) Memory leak (CVE-ID: CVE-2021-3690)

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak when processing incoming PONG messages. A remote attacker can force the application to leak memory by sending an websocket PONG message and perform denial of service attack.


6) Heap-based buffer overflow (CVE-ID: CVE-2021-43527)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when handling DER-encoded DSA or RSA-PSS signatures. A remote attacker can send specially crafted signatures encoded within CMS, S/MIME, PKCS #7, or PKCS #12 to the application, trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


7) Code Injection (CVE-ID: CVE-2022-22965)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation. A remote attacker can send a specially crafted HTTP request to the affected application and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Note, the vulnerability is being actively exploited in the wild.

This vulnerability was dubbed "Spring4Shell".


8) Improper input validation (CVE-ID: CVE-2021-29921)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The vulnerability exists due to improper input validation within the Python interpreter and runtime (CPython) component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.


9) Code Injection (CVE-ID: CVE-2022-22947)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a code injection attack when the Gateway Actuator endpoint is enabled. A remote attacker can send a specially crafted HTTP POST request and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
