Ignitetechnologies/Privilege-Escalation is a curated cheat sheet that catalogues Linux privilege escalation vectors — from sudo misconfigurations to SUID binaries — for CTF players and authorized pentesters.
| Tool | Ignitetechnologies/Privilege-Escalation — a categorized cheat sheet indexing privilege escalation techniques against dozens of VulnHub and CTF walkthroughs |
| Category | Reference / cheatsheet repository for offensive security training |
| Primary Use | Study aid for OSCP preparation and CTF practice, mapping techniques like SUID abuse, cronjob misuse, and capabilities to specific lab machines |
| Safe Use | Intended for authorized practice on deliberately vulnerable VulnHub VMs, personal labs, and engagement environments with written permission; educational and documentary reference only |
| Telemetry Note | Purely a documentation resource — it executes nothing itself, so it leaves no footprint; defenders benefit from the same catalogue when auditing sudo rules, SUID files, and writable paths |
Ignitetechnologies/Privilege-Escalation, maintained by the HackingArticles team, is not a scanner or exploit framework but a structured reference that maps privilege escalation classes to concrete lab practice. With roughly 3,600 stars and a topic list spanning cheatsheet, ctf, oscp-prep, and vulnhub, it occupies a specific niche in the training ecosystem: the gap between reading about a technique and knowing which deliberately vulnerable machine demonstrates it. For professionals preparing for the OSCP or mentoring juniors, that mapping is the real product.
The repository's architecture is a single long-form README organized as a table of contents with anchor links covering more than twenty escalation categories. The core sections include Abusing Sudo Rights, SUID Bit, Kernel Exploit, Path Variable, Enumeration, MySQL, Cronjob, Wildcard Injection, Capabilities, and writable /etc/passwd. Additional sections cover Docker, Chkrootkit, NFS, Redis, LXD, Exim, JSON, and Apache2 writable configurations, which reflects how far the privesc surface extends beyond the classic Linux local vectors.
Each category is rendered as a table with three columns: machine name, the relevant file or binary, and a link to a full walkthrough on hackingarticles.in. In the sudo section, for example, entries pair vulnerable VMs with the specific binaries whose sudo rules were overly permissive — apt-get, awk, cat, git, nmap, perl, pip, vim, zip, tcpdump, dpkg, and strace among them. The pattern that emerges is GTFOBins-style: shells and interpreters that can be coerced into spawning a privileged process when granted sudo without proper restriction.
The SUID Bit section follows the same convention, indexing lab machines against the binaries that carried the setuid bit. Here the recurring names are cp, find, script, nmap, doas, python 2.7, php7.2, systemctl, cpulimit, nohup, and even base32 and a micro editor. The educational value is the frequency distribution: seeing find and cp appear repeatedly teaches a student which binaries deserve first attention during enumeration, which is exactly the triage instinct an examiner wants to build.
The Kernel Exploit section adds a third dimension by correlating lab machines with the affected kernel or subsystem version and an Exploit-DB reference ID. Entries span older Linux kernels (2.6.17 through the Ubuntu 12.04–15.04 era), an RDS protocol local privilege escalation, a FreeBSD SYSRET issue, and Apport/Abrt service flaws. For defenders this section doubles as a historical inventory of why unpatched kernels were such reliable footholds for so many years, and why CIS-style patching baselines exist today.
What the repository implicitly teaches is methodology rather than any single technique. The section list itself reads like a checklist: after landing a low-privilege shell, the canonical enumeration targets are sudo rules, SUID/SGID binaries, kernel version, cron schedules, capabilities, writable system files, misconfigured services such as Redis, MySQL, Exim, and container escape surfaces like Docker and LXD. A junior reading the table of contents top to bottom is effectively internalizing the same workflow automated by tools like LinPEAS, but grounded in documented, reproducible lab outcomes.
From an authorized-workflow standpoint, the material is best used alongside the referenced VulnHub machines in an isolated lab network. The walkthrough links are hosted externally at hackingarticles.in, so the repository functions as an index while the detailed step-by-step narrative lives on the blog. That separation is worth noting operationally: the repo itself contains no exploit code, no payloads, and no tooling — only metadata linking techniques, binaries, and educational scenarios.
The breadth of service-specific sections also reveals how privilege escalation curricula have evolved. Classic topics like Cronjob abuse and Wildcard Injection (tar's argument-parsing quirks being the canonical example) sit beside newer container-era vectors such as Docker group membership and LXD socket exposure. Redis and NFS sections cover trust-boundary failures in data services, while Chkrootkit and Exim entries document privilege escalation through vulnerable installed software rather than misconfiguration — a reminder that patch management is itself a privesc control.
For blue teams, the catalogue is equally instructive in reverse. Every entry is a detection or hardening hypothesis: restrictive sudoers policy, regular SUID audits with something like find / -perm -4000, filesystem integrity monitoring on /etc/passwd and writable scripts, cron hygiene, dropping unneeded capabilities, and patching the kernel and service versions listed in the kernel section. The same tables that guide an attacker's enumeration order in a lab guide a defender's audit order in production, which is a defensible reason to keep this reference in a professional bookmark set.
There are limitations worth acknowledging. The repository has no license declared, it is English-language but informal in tone, and the lab machines skew heavily toward older VulnHub content with dated kernels, so the kernel section should be read as historical education rather than current tradecraft. Some link rot is inevitable in a catalogue this large, and the tables are not automated — there is no tooling to validate whether each walkthrough remains accessible.
In sum, Privilege-Escalation from Ignitetechnologies is a well-starred, genuinely useful study index rather than a tool in the executable sense. Its value is compressing hundreds of hours of lab walkthroughs into a technique-to-machine concordance that builds pattern recognition for authorized testing, OSCP candidates, and defenders who want to understand the misconfiguration landscape they are paid to eliminate. Used as intended — against deliberately vulnerable VMs in a private lab — it is a solid component of a structured training path.
