SB2020011484 - Multiple vulnerabilities in Oracle Business Intelligence Enterprise Edition

Description

This security bulletin contains information about 4 vulnerabilities.

1) Improper input validation (CVE-ID: CVE-2020-2531)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

The vulnerability exists due to improper input validation within the BI Platform Security component in Oracle Business Intelligence Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.

2) Improper input validation (CVE-ID: CVE-2020-2535)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

The vulnerability exists due to improper input validation within the Analytics Server component in Oracle Business Intelligence Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.

3) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2019-1559)

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote attacker to decrypt sensitive information.

The vulnerability exists due to the way an application behaves, when it receives a 0-byte record with invalid padding compared to the record with an invalid MAC, which results in padding oracle. A remote attacker can decrypt data.

Successful exploitation of the vulnerability requires that the application is using "non-stitched" ciphersuites and calls SSL_shutdown() twice (first, via a BAD_RECORD_MAC and again via a CLOSE_NOTIFY). 

4) Improper input validation (CVE-ID: CVE-2020-2537)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote non-authenticated attacker 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 non-authenticated attacker can exploit this vulnerability to read and manipulate data.
