CWE-ID:
CWE-94 - Improper Control of Generation of Code ('Code Injection')
Exploit availability: No
DescriptionThe 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.

EUVDB-ID: #VU56613
Risk: Medium
CVSSv3.1: 6.2 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-22946
CWE-ID:
CWE-319 - Cleartext Transmission of Sensitive Information
Exploit availability: No
DescriptionThe 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.
