Why this priority: Low severity, with no exploitation signal.
Published · Updated · NVD status: Received
What it is
Input is pasted into a directory query, letting an attacker change what it returns.
How it is reached
An attacker can exploit it over the network, with an ordinary user account, and nobody has to click anything. Success also depends on conditions the attacker does not fully control.
What an attacker gains
The direct impact is limited: partial access to data or a partial outage. In practice, this kind of flaw lets an attacker read or change records in the data store behind the application.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- Upgrade meeting-room-booking-system mrbs-code to 1.13.0 or later.
- Until it is patched, review who holds accounts that can reach it.
Description from NVD
MRBS before 1.13.0 contains an LDAP injection vulnerability in web/lib/MRBS/Auth/AuthLdap.php that interpolates unescaped login usernames into DN search and group-membership filters. Attackers with valid directory credentials outside the required group can submit crafted usernames that make the group filter always true, bypassing access restrictions.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Services that build database or directory queries. The flaw sits between the application and its data store.
- Databases. The flaw sits between the application and its data store.
Trust boundaries in play
- Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
- Between the application and its data store. An attacker who crosses it can read or change records in the data store behind the application.
Questions to answer about your own systems
- Where does meeting-room-booking-system mrbs-code run in your systems, and at which version?
- Which of those instances can be reached from the internet or partner networks?
- What can it reach once compromised: which data stores, secrets and services?
