"CVE-2019-2763
8.2 AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N
Easily exploitable vulnerability allows unauthenticated attacker with
network access via HTTP to compromise the affected system. Successful
attacks of this vulnerability can result in unauthorized access to
critical data or complete access to all the affected system's
accessible data as well as unauthorized update, insert or delete
access to some of the affected system's accessible data.
Affects:
o Oracle Hospitality Gift and Loyalty 9.0.0, 9.1.0
CVE-2019-2833
7.7 AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N
Easily exploitable vulnerability allows low privileged attacker
having Import/Export privilege with network access via HTTP to
compromise the affected system. While the vulnerability is in the
affected system, attacks may significantly impact additional
products. Successful attacks of this vulnerability can result in
unauthorized access to critical data or complete access to all the
affected system's accessible data.
Affects:
o Oracle Hospitality Simphony 18.2.1
CVE-2019-2836
7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Easily exploitable vulnerability allows unauthenticated attacker with
network access via HTTP to compromise the affected system. Successful
attacks of this vulnerability can result in unauthorized access to
critical data or complete access to all the affected system's
accessible data.
Affects:
o Oracle Hospitality Simphony 18.2.1" [2]
MITIGATION
Oracle states:
"Due to the threat posed by a successful attack, Oracle strongly
recommends that customers apply CPU fixes as soon as possible. Until
you apply the CPU fixes, it may be possible to reduce the risk of
successful attack by blocking network protocols required by an
attack. For attacks that require certain privileges or access to
certain packages, removing the privileges or the ability to access
the packages from users that do not need the privileges may help
reduce the risk of successful attack. Both approaches may break
application functionality, so Oracle strongly recommends that
customers test changes on non-production systems. Neither approach
should be considered a long-term solution as neither corrects the
underlying problem." [1]
