Vulnerability in crp in Hewlett Packard Apollo Domain OS SR10 through SR10.3 allows remote attackers to gain root privileges via insecure system calls, (1) pad_$dm_cmd and (2) pad_$def_pfk().
Remote attackers can gain root privileges on vulnerable Hewlett Packard Apollo Domain OS systems (SR10 through SR10.3) due to insecure system calls within the crp component. This allows for complete system compromise, potentially leading to data breaches and system outages.
Step 1: Target Identification: The attacker identifies a vulnerable Hewlett Packard Apollo Domain OS system running SR10 through SR10.3. This likely involves network scanning and version detection.
Step 2: Payload Crafting: The attacker crafts a malicious payload designed to exploit either pad_$dm_cmd or pad_$def_pfk(). This payload will likely be designed to overwrite critical memory locations.
Step 3: Payload Delivery: The attacker sends the crafted payload to the vulnerable system, likely through a network connection, potentially using a custom exploit or a tool designed for this purpose.
Step 4: System Call Trigger: The attacker triggers the vulnerable system call (pad_$dm_cmd or pad_$def_pfk()) with the crafted payload as input.
Step 5: Code Execution: The crafted payload, due to the lack of input validation, causes a memory corruption vulnerability (e.g., buffer overflow). This allows the attacker to overwrite critical memory locations and gain control of the program's execution flow.
Step 6: Privilege Escalation: The attacker's controlled code execution allows them to execute arbitrary commands with root privileges, effectively compromising the system.
The vulnerability lies within the crp (likely a privileged process) component of Hewlett Packard Apollo Domain OS. Specifically, the system calls pad_$dm_cmd and pad_$def_pfk() are susceptible to exploitation. The root cause is likely a lack of proper input validation and/or insufficient bounds checking on data passed to these system calls. This could lead to a buffer overflow or other memory corruption issues. By crafting malicious input, an attacker can overwrite critical memory regions, potentially including the stack or heap, to execute arbitrary code with root privileges. The age of the vulnerability suggests a design flaw related to how data is handled within these system calls, likely related to the parsing and processing of user-supplied data. This could involve incorrect handling of data lengths, format strings, or other input parameters, allowing an attacker to control program execution. The crp process, being privileged, elevates the impact significantly.
Due to the age of the vulnerability, it is unlikely to be directly associated with specific modern APT groups. However, any threat actor targeting legacy systems could potentially leverage this. The vulnerability is not listed on the CISA KEV.
Monitor network traffic for unusual patterns or requests to the vulnerable system calls (pad_$dm_cmd or pad_$def_pfk()).
Analyze system logs for suspicious activity, such as unexpected process behavior or errors related to the crp component.
Implement file integrity monitoring to detect any unauthorized modification of system files or binaries.
Use intrusion detection/prevention systems (IDS/IPS) with signatures that detect known exploit attempts against this vulnerability (if available).
Review system call logs for calls to pad_$dm_cmd and pad_$def_pfk() with unusual parameters or data sizes.
Upgrade to a patched version of the operating system (if available). Given the age of the OS, this may not be possible.
If patching is not possible, isolate the affected systems from the network to limit exposure.
Implement strong network segmentation to restrict access to the affected systems.
Review and harden the system's security configuration, including access controls and user privileges.
Implement a robust intrusion detection and prevention system (IDS/IPS) to monitor for and block exploit attempts.
Consider replacing the affected system with a more modern and secure operating system.
If the system is critical, consider a security audit to identify and mitigate any remaining risks.
