IntelliShield has updated this alert to include additional information to address the Novell File Reporter NFRAgent.exe VOL tag remote code execution vulnerability.
Description
Novell File Reporter contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system.
The vulnerability is due to insufficient bounds checking of user-supplied data by the affected software. An unauthenticated, remote attacker could exploit the vulnerability by transmitting a crafted request to the affected software. Successful exploitation could allow the attacker to execute arbitrary code with SYSTEM privileges on the targeted system.
Novell has not confirmed the vulnerability and updates are not available.
Warning Indicators
Novell File Reporter versions 1.0.2 and prior are vulnerable.
IntelliShield Analysis
To exploit the vulnerability, the attacker must send a request to the targeted system. To transmit the requests, the attacker must have access to the trusted network. This access requirement could limit likelihood of a successful exploit.
Vendor Announcements
Vendor announcements are not available.
Impact
An unauthenticated, remote attacker could exploit the vulnerability to execute arbitrary code on a targeted system. If the user has elevated privileges, code execution could allow a complete system compromise.
Technical Information
The vulnerability is in NFRAgent.exe, which communicates with the agent component that runs by default on TCP port 3037. While processing the tags inside the VOL element, the affected component performs insufficient bounds checking on user-supplied input data. Due to this error, data is copied to the fixed-sized buffer by the affected software, which may trigger a buffer overflow and cause memory corruption.
An unauthenticated, remote attacker could exploit the vulnerability by transmitting a crafted request to the affected software. Successful exploitation could allow the attacker to execute arbitrary code with SYSTEM privileges on the targeted system.
Safeguards
Administrators are advised to implement an intrusion prevention system (IPS) or intrusion detection system (IDS) to help detect and prevent attacks that attempt to exploit this vulnerability.
Administrators are advised to contact the vendor regarding future updates and releases.
Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.
Administrators are advised to monitor affected systems.
Patches/Software
Patches and software updates are not available.
