VAR-200907-0160
Vulnerability from variot - Updated: 2025-04-10 23:19The OAmon.sys kernel driver 3.1.0.0 and earlier in Tall Emu Online Armor Personal Firewall AV+ before 3.5.0.12, and Personal Firewall 3.5 before 3.5.0.14, allows local users to gain privileges via crafted METHOD_NEITHER IOCTL requests to \Device\OAmon containing arbitrary kernel addresses, as demonstrated using the 0x830020C3 IOCTL. Online Armor Personal Firewall is prone to a local privilege-escalation vulnerability. An attacker may exploit this issue to execute arbitrary code with elevated privileges, which may facilitate a complete compromise of the affected computer. Online Armor Personal Firewall 3.5.0.12 and prior versions are affected. Online Armor Personal Firewall AV+ is also vulnerable. Local non-privileged users can write arbitrary data to arbitrary addresses, resulting in the execution of arbitrary kernel mode code. .text:00013E8D @@ioctl_830020C3: .text:00013E8D mov eax, [ebp+OutputBuffer]; UserBuffer .text:00013E90 mov dword ptr [eax], 1 ; UserBuffer[0] = 1 .text:00013E96 mov eax , edi.text:00013E98 mov dword ptr [eax], 4.text:00013E9E jmp @@return_false …

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
