Openedge: Improper Neutralization of Special Elements in Output Used by a Downstream Component
CVE-2023-34203 is a high-severity improper neutralization of special elements in output used by a downstream component vulnerability in Openedge from Progress Software, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists versions 11.7.16, 12.2.12, 12.7 as the first without the flaw, so updating Openedge to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.06% chance of exploitation within 30 days, higher than 65% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Openedge to 11.7.16 or 12.2.12 or 12.7, whichever matches your release line, or a later version.
- Update Openedge Explorer to 12.7 or a later version.
- Update Openedge Management to 12.7 or a later version.

Official description
In Progress OpenEdge OEM (OpenEdge Management) and OEE (OpenEdge Explorer) before 12.7, a remote user (who has any OEM or OEE role) could perform a URL injection attack to change identity or role membership, e.g., escalate to admin. This affects OpenEdge LTS before 11.7.16, 12.x before 12.2.12, and 12.3.x through 12.6.x before 12.7.

The underlying weakness: Improper Neutralization of Special Elements in Output Used by a Downstream Component
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
How developers prevent this class of flaw
- Programming languages and supporting technologies might be chosen which are not subject to these issues.
- Utilize an appropriate mix of allowlist and denylist parsing to filter control-plane syntax from all input.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
