Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Deserialization of Untrusted Data

EUVDB-ID: #VU28158

Risk: High

CVSSv4.0: 8.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]

CVE-ID: CVE-2020-9484

CWE-ID: CWE-502 - Deserialization of Untrusted Data

Exploit availability: Yes

Description

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

The vulnerability exists due to insecure input validation when processing serialized data in uploaded files names. A remote attacker can pass specially crafted file name to the application and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that the server is configured to use PersistenceManager with a FileStore and the attacker knows relative file path from storage location.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Oracle Hospitality Guest Access: 4.2.0 - 4.2.1

2) Operation on a Resource after Expiration or Release

EUVDB-ID: #VU34161

Risk: High

CVSSv4.0: 8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2019-17638

CWE-ID: CWE-672 - Operation on a Resource after Expiration or Release

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to #BASIC_IMPACT#.

In Eclipse Jetty, versions 9.4.27.v20200227 to 9.4.29.v20200521, in case of too large response headers, Jetty throws an exception to produce an HTTP 431 error. When this happens, the ByteBuffer containing the HTTP response headers is released back to the ByteBufferPool twice. Because of this double release, two threads can acquire the same ByteBuffer from the pool and while thread1 is about to use the ByteBuffer to write response1 data, thread2 fills the ByteBuffer with response2 data. Thread1 then proceeds to write the buffer that now contains response2 data. This results in client1, which issued request1 and expects responses, to see response2 which could contain sensitive data belonging to client2 (HTTP session ids, authentication credentials, etc.).

Mitigation

Install update from vendor's website.
