QNX Neutrino RTOS crttrap privilege elevation
| qnx-crttrap-privilege-elevation (24560) |  High Risk |
Description:
QNX Neutrino RTOS could allow a local attacker to gain elevated privileges on the system, caused by a vulnerability in the crttrap command. An attacker could modify the LD_LIBRARY_PATH environment variable to cause the crttrap command to load malicious attacker-supplied libraries, allowing the attacker to gain root privileges on the system.
Note: The system must be in text mode in order for this vulnerability to be exploited.
