Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Resource management error (CVE-ID: CVE-2021-22569)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application. protobuf-java allowes the interleaving of
com.google.protobuf.UnknownFieldSet fields in such a way that would be
processed out of order. A small malicious payload can occupy the parser
for several minutes by creating large numbers of short-lived objects
that cause frequent, repeated pauses. A remote attacker can trick the victim into passing specially crafted data to the application and perform a denial of service attack.
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) 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.
5) 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".
