A vulnerability classified as problematic was found in RT-Thread up to 5.1.0. This vulnerability allows the function sys_device_close/sys_device_control/sys_device_find/sys_device_init/sys_device_open/sys_device_read/sys_device_register/sys_device_write/sys_event_delete/sys_event_recv/sys_event_send/sys_mb_delete/sys_mb_recv/sys_mb_send/sys_mb_send_wait/sys_mq_recv/sys_mq_send/sys_mq_urgent/sys_mutex_delete/sys_mutex_release/sys_mutex_take/sys_rt_timer_control/sys_rt_timer_delete/sys_rt_timer_start/sys_rt_timer_stop/sys_sem_delete/sys_sem_release/sys_sem_take/sys_shmat/sys_shmdt/sys_thread_create/sys_thread_delete/sys_thread_startup/sys_timer_delete/sys_timer_gettime/sys_timer_settime of the file rt-thread/components/lwp/lwp_syscall.c.
The manipulation of the argument arg[0] leads to information disclosure. An attack has to be approached locally. With a CVSS score of 4.8, this vulnerability falls under the medium severity category, making it imperative for organizations to address it in their patch cycles.
Risk to organizations includes potential unauthorized access to sensitive information, presenting a tangible threat to data confidentiality. Therefore, organizations should prioritize patching immediately.
As of now, there is no public exploit confirmed for this vulnerability, and it is not actively exploited, which provides a window for remediation efforts.
Organizations must remain vigilant and implement necessary updates to mitigate potential risks associated with this vulnerability.
Vulnerability Details
The vulnerability affects RT-Thread versions up to 5.1.0. The specific function impacted involves a series of device and thread management calls within the RT-Thread system. The CVSS 4.0 score indicates a medium severity classification, highlighting that while the exploit requires local access, the consequences can be significant.
The vulnerability allows for potential information disclosure, categorized under CWE-200 (Information Exposure) and CWE-284 (Improper Access Control).
Technical Analysis
The root cause of this vulnerability lies in the insufficient validation of the arguments passed to the system call functions. Attackers may leverage this flaw to gain unauthorized access to sensitive information, albeit only when they have local access to the system.
The attack vector is classified as local, with low complexity, requiring low privileges and no user interaction. The impact on confidentiality is low, indicating that while information may be disclosed, it does not affect integrity or availability.
Risk & Impact Analysis
The risk to organizations includes potential unauthorized access to sensitive information. As the vulnerability requires local access, the blast radius is somewhat limited. However, it is essential for organizations to understand that even medium-severity vulnerabilities can lead to critical breaches if left unaddressed.
The urgency for remediation is classified as medium, emphasizing that while immediate action is not required, organizations should plan to address this vulnerability in their next patch cycle.
