Description

This security bulletin contains information about 9 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2020-10693)

The vulnerability allows a remote attacker to modify files on the system.

The vulnerability exists due to insufficient validation of user-supplied input when handling user-controlled data in error messages. A remote attacker can bypass input sanitation (escaping, stripping) controls.


2) Input validation error (CVE-ID: CVE-2020-13956)

The vulnerability allows a remote attacker to compromise the affected application.

The vulnerability exists due to insufficient validation of user-supplied input in Apache HttpClient. A remote attacker can pass request URIs to the library as java.net.URI object and force the application to pick the wrong target host for request execution.


3) Resource exhaustion (CVE-ID: CVE-2021-36090)

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 when processing ZIP archives. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


4) Path traversal (CVE-ID: CVE-2022-23457)

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in getValidDirectoryPath. A remote attacker can send a specially crafted HTTP request and allow control-flow bypass checks to be defeated.


5) Use-after-free (CVE-ID: CVE-2022-43680)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error caused by overeager destruction of a shared DTD in XML_ExternalEntityParserCreate. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.


6) Insecure library loading (CVE-ID: CVE-2021-36770)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a logic error in the Encode.pm script. A local user can place a malicious library into the current working directory and escalate privileges on the system.


7) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2020-11987)

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.


8) Code Injection (CVE-ID: CVE-2022-42889)

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

The vulnerability exists due to an insecure variable interpolation when processing untrusted input. A remote attacker can send a specially crafted input and execute arbitrary code on the target system.

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

Note, the vulnerability was dubbed Text4shell.


9) Deserialization of Untrusted Data (CVE-ID: CVE-2022-45047)

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

The vulnerability exists due to insecure input validation when processing serialized data within the org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider class. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.

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