Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Use of a broken or risky cryptographic algorithm
EUVDB-ID: #VU17860
Risk: Low
CVSSv3.1: 2.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-1559
CWE-ID:
CWE-327 - Use of a Broken or Risky Cryptographic Algorithm
Exploit availability: No
DescriptionThe 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).Mitigation
Update to versions 7.1.25, 8.0.20, 8.1.8, or 9.0.2.
Vulnerable software versionsPalo Alto PAN-OS: 7.1.0 - 9.0.4
