Description

This security bulletin contains information about 11 secuirty vulnerabilities.


1) Cleartext storage of sensitive information (CVE-ID: CVE-2022-34339)

The vulnerability allows a remote user to gain access to potentially sensitive information.

The vulnerability exists due to IBM Cognos Analytics stores user credentials in plain clear text. A remote user can gain unauthorized access to sensitive information on the system.


2) Out-of-bounds read (CVE-ID: CVE-2021-3712)

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

The vulnerability exists due to a boundary condition when processing ASN.1 strings related to a confusion with NULL termination of strings in array. A remote attacker can pass specially crafted data to the application to trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.


3) Buffer overflow (CVE-ID: CVE-2021-3711)

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

The vulnerability exists due to a boundary error in EVP_PKEY_decrypt() function within implementation of the SM2 decryption. A remote attacker can send specially crafted SM2 content for decryption to trigger a buffer overflow by 62 bytes and execute arbitrary code on the target system.

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


4) Cryptographic issues (CVE-ID: CVE-2021-4160)

The vulnerability allows a remote attacker to decrypt TLS traffic.

The vulnerability exists due to BN_mod_exp may produce incorrect results on MIPS. A remote attacker can decrypt TLS traffic. According to vendor, multiple EC algorithms are affected, including some of the TLS 1.3 default curves. 

Successful exploitation of the vulnerability requires certain pre-requisites for attack, such as obtaining and  reusing private keys. 


5) Path traversal (CVE-ID: CVE-2021-29425)

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

The vulnerability exists due to input validation error within the FileNameUtils.normalize method when processing directory traversal sequences, such as "//../foo", or "\..foo". A remote attacker can send a specially crafted request and verify files availability in the parent folder.


6) Resource management error (CVE-ID: CVE-2021-3733)

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 within the AbstractBasicAuthHandler class in urllib. A remote attacker with control over the server can perform regular expression denial of service attack during authentication.


7) Infinite loop (CVE-ID: CVE-2021-3737)

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

The vulnerability exists due to infinite loop. A remote attacker who controls a malicious server can force the client to enter an infinite loop on a 100 Continue response.


8) CRLF injection (CVE-ID: CVE-2022-0391)

The vulnerability allows a remote attacker to inject arbitrary data in server response.

The vulnerability exists due to insufficient validation of attacker-supplied data within the urllib.parse module in Python. A remote attacker can pass specially crafted data to the application containing CR-LF characters and modify application behavior.


9) Prototype pollution (CVE-ID: CVE-2021-43138)

The vulnerability allows a remote attacker to escalate privileges within the application.

The vulnerability exists due to improper input validation when handling data passed via the mapValues() method. A remote attacker can send a specially crafted request and escalate privileges within the application.


10) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2022-24758)

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to software stores sensitive information into log files, such as authentication cookies and header values when a 5xx error is triggered. A local user can read the log files and gain access to sensitive data.


11) Cross-site scripting (CVE-ID: CVE-2020-4051)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data in the Editor's LinkDialog plugin. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
