Loading vulnerability…
CVE-2019-17558 is a remote code execution vulnerability affecting Apache Solr 5.0.0 through 8.3.1 in the VelocityResponseWriter feature. The issue arises because Velocity templates can be rendered from templates stored in a configset's velocity/ directory or, if explicitly enabled, supplied via request parameters. A user-defined configset may therefore contain malicious renderable templates. Parameter-supplied templates are disabled by default, but can be enabled with params.resource.loader.enabled=true on a configured response writer; defining such a response writer requires Configuration API access. In vulnerable versions, insufficient restriction of template sources allows attacker-controlled Velocity template content to be executed by Solr, leading to server-side code execution.

If you can’t patch tonight, do this now.
params.resource.loader.enabled. Restrict Configuration API access to trusted administrators only. Limit configset upload capability to authenticated, trusted users and ensure only trusted configsets are used for template rendering. Review deployed configsets for malicious or unnecessary Velocity templates in velocity/ directories.Patch, then assume compromise.

This repository is a multi-module Python offensive framework centered on exploiting HiSilicon DVR/NVR/IP camera devices via CVE-2020-25078, then managing compromised hosts through a Flask/SocketIO web panel. It is not a simple single-file PoC: it includes a control server (server.py), persistence and post-exploitation tooling, credential attacks, recon modules, web vulnerability scanners, network service checks, pivoting, reverse shell support, and a SQLite-backed datastore. Core exploit logic is in exploit.py and scanner.py. exploit.py probes numerous traversal/disclosure paths such as /../../.../mnt/mtd/Config/Account1 and related config/system files, parses returned content with multiple regex patterns to recover credentials, fingerprints device families, and falls back to known default credentials when disclosure succeeds but parsing does not. scanner.py operationalizes this by scanning IPs/CIDRs and common ports, checking liveness, fingerprinting likely cameras, invoking the CVE-2020-25078 checks, and storing recovered credentials in cameras.db. Post-exploitation capability is substantial. telnet_client.py provides raw Telnet login and command execution. botnet.py fans out commands across stored hosts. persistence.py installs SSH authorized_keys, cron, rc.local, init.d, systemd, inittab telnetd, and bind-shell style persistence. reverse_shell.py generates many Linux/IoT reverse shell one-liners and runs listeners. pivot_chain.py and socks_pivot.py support chained execution and local SOCKS5 pivoting through compromised hosts. Additional modules broaden scope beyond the HiSilicon exploit: brute.py and cred_spray.py perform credential attacks across Telnet, SSH, FTP, HTTP, SMB, databases, VNC, LDAP, WinRM, and more; network_exploit.py checks for exposed/misconfigured services and some well-known vulnerabilities such as MS17-010 and BlueKeep; web_exploit.py, web_cves.py, web_bugs.py, and web_brute.py scan websites for exposed files, CMS fingerprints, generic bug classes, and multiple CVE signatures. Recon/intel support includes ASN, DNS, GeoIP, JARM, WAF detection, proxy/Tor rotation, screenshot grabbing from camera snapshot endpoints, and Telegram/Discord/AbuseIPDB integrations. The repository structure is coherent and functional, with many CLI-capable modules and a central web UI in templates/index.html. Overall, this is an operational exploit-and-post-exploitation toolkit focused on HiSilicon IoT devices but expanded into a broader C2-style offensive platform.
This repository contains a single Metasploit module (modules/exploits/multi/http/solr_velocity_rce.rb) that exploits CVE-2019-17558, a remote code execution vulnerability in Apache Solr versions up to 8.3.0. The exploit leverages the Velocity Response Writer feature, which can be enabled via the Solr Config API, to inject and execute arbitrary Velocity templates. These templates can be crafted to execute system commands, allowing the attacker to run arbitrary code on the Solr server. The module supports multiple payloads, including reverse shells and command execution, across Linux, Unix, and Windows platforms. It requires network access to the Solr HTTP(S) interface and, if authentication is enabled, valid credentials. The exploit is weaponized, supporting a range of payloads and platforms, and is suitable for use in penetration testing and red teaming engagements. The main endpoints targeted are the Solr core's /config and /select HTTP API paths.
This repository is a comprehensive exploit library (exphub) containing operational exploit scripts for a wide range of high-profile vulnerabilities affecting popular enterprise software. The structure is organized by product (e.g., drupal/, f5/, fastjson/, jboss/, nexus/, ofbiz/, shiro/, solr/, spring/, struts2/, tomcat/, weblogic/), with each directory containing Python or Java scripts for specific CVEs. The scripts are primarily remote code execution (RCE) exploits, but also include file read, webshell upload, SSRF, and administrative bypasses. Many scripts provide interactive shells or allow arbitrary command execution, and some require authentication. The repository includes both proof-of-concept (POC) and full exploit scripts, with detailed usage instructions embedded in the code and readme files. The attack vector is predominantly network-based, targeting HTTP(S) endpoints, and the scripts are suitable for both vulnerability validation and exploitation. The codebase is mature, with operational exploits for each vulnerability, and is a valuable resource for penetration testers and red teamers.
