Description

This security bulletin contains information about 4 secuirty vulnerabilities.

1) Input validation error (CVE-ID: CVE-2021-22096)

The vulnerability allows a remote attacker to modify existing log records.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can pass specially crafted input to the application and inject arbitrary records into log files.

2) 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.

3) 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.

4) Resource exhaustion (CVE-ID: CVE-2021-42340)

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

The vulnerability exists due memory leak when processing HTTP connections. A remote attacker can initiate multiple HTTP connections with the web server and consume all available memory on the system.
