Summary
Portwell Engineering Toolkits version 4.8.2 contains a buffer overflow vulnerability (CWE-119) that allows a local attacker with low privileges to escalate privileges or cause a denial-of-service condition on the affected system.
What this means
What could happen
An attacker with local access to a machine running this toolkit could gain administrative privileges or crash the engineering workstation, potentially disrupting engineering work or process management activities.
Who's at risk
Engineering and manufacturing organizations using Portwell Engineering Toolkits 4.8.2 on engineering workstations. This affects technicians and engineers in energy and manufacturing sectors who rely on these tools for process control system configuration and maintenance.
How it could be exploited
An attacker with a low-privilege local account on a system running the vulnerable toolkit could exploit a buffer overflow to run commands with higher privileges (privilege escalation) or cause the application to crash (denial of service). The attacker does not need user interaction or valid administrative credentials.
Prerequisites
- Local user account access to a machine running Portwell Engineering Toolkits version 4.8.2
- No user interaction required
- Low privilege user account is sufficient
No patch availableLocal privilege escalation possibleAffects engineering workstations used to configure control systemsLow attack complexityLow privilege requirements for exploitation
Exploitability
Low exploit probability (EPSS 0.0%)
