Type: CWE-78 (Improper Neutralization of Special Elements used in an OS Command
('OS Command Injection'))
Component: backend
Report confidence: Confirmed
Solution status: Fixed by vendor
Last affected revision: OX App Suite backend 7.10.6-rev50
First fixed revision: OX App Suite backend 7.10.6-rev51
Discovery date: 2023-08-08
Solution date: 2023-09-14

CVE: CVE-2023-29048
CVSS: 8.8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
Details:
OXMF templates allow remote code execution. A component for parsing OXMF
templates could be abused to execute arbitrary system commands that would be
executed as the non-privileged runtime user.
Risk:
Users and attackers could run system commands with limited privilege to gain
unauthorized access to confidential information and potentially violate
integrity by modifying resources. No publicly available exploits are known.
Solution:
The template engine has been reconfigured to deny execution of harmful commands
on a system level.

CVSS: 7.6 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:L)
Details:
LDAP filter injection vulnerability in Contacts Provider LDAP. The optional
"LDAP contacts provider" could be abused by privileged users to inject LDAP
filter strings that allow to access content outside of the intended hierarchy.
Risk:
Unauthorized users could break confidentiality of information in the directory
and potentially cause high load on the directory server, leading to denial of
service. No publicly available exploits are known.
Solution:
Encoding has been added for user-provided fragments that are used when
constructing the LDAP query.
