Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU17698
Risk: Low
CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-16881
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in the imptcp module due to insufficient validation of user-supplied input. A remote attacker can send a specially crafted message to the imptcp socket that submits malicious input and cause the affected software to crash, resulting in a DoS condition.
MitigationInstall updates from vendor's website.

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).Install updates from vendor's website.

EUVDB-ID: #VU20066
Risk: Low
CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-3888
CWE-ID:
CWE-312 - Cleartext Storage of Sensitive Information
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to the Connectors.executeRootHandler:402 logs the HttpServerExchange object at ERROR level using UndertowLogger.REQUEST_LOGGER.undertowRequestFailed(t, exchange), which includes logging of user credentials. A local user can view contents of log files and gain access to credentials in plain text that are stored in them.
