What this means
- Exposure
- Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
- Impact
- An attacker can alter some data and take the service offline. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- A “../” sequence in a path lets an attacker climb the directory tree and reach other files.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
