SB2021042543 - Multiple vulnerabilities in Oracle Business Intelligence Enterprise Edition

Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Improper input validation (CVE-ID: CVE-2021-2152)

The vulnerability allows a remote privileged user to read and manipulate data.

The vulnerability exists due to improper input validation within the Analytics Web General component in Oracle Business Intelligence Enterprise Edition. A remote privileged user can exploit this vulnerability to read and manipulate data.

2) Improper input validation (CVE-ID: CVE-2021-2191)

The vulnerability allows a remote authenticated user to read and manipulate data.

The vulnerability exists due to improper input validation within the Analytics Actions component in Oracle Business Intelligence Enterprise Edition. A remote authenticated user can exploit this vulnerability to read and manipulate data.

3) Cross-site scripting (CVE-ID: CVE-2020-11022)

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 regex operation in "jQuery.htmlPrefilter". A remote attacker can pass specially crafted data to the application that uses .html()</code>, <code>.append() or similar methods for it and execute arbitrary JavaScript 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.

4) Cross-site scripting (CVE-ID: CVE-2019-0221)

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 within SSI printenv command, when parsing URI. 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.

Example:

http://[host]/printenv.shtml?%3Cscript%3Ealert(%27xss%27)%3C/script%3E

5) NULL pointer dereference (CVE-ID: CVE-2020-1971)

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

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via the API functions TS_RESP_verify_response and TS_RESP_verify_token). If an attacker can control both items being compared then that attacker could trigger a crash. For example if the attacker can trick a client or server into checking a malicious certificate against a malicious CRL then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a certificate. This checking happens prior to the signatures on the certificate and CRL being verified. OpenSSL's s_server, s_client and verify tools have support for the "-crl_download" option which implements automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will accept and hence trigger this attack.

6) Improper Authentication (CVE-ID: CVE-2020-9480)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in when processing authentication requests on Apache Spark master configured to require authentication (spark.authenticate) via a shared secret. A remote non-autenticated attacker can send a specially crafted RPC request without the shared key, bypass authentication process and start application resources on a Spark cluster.
