{% hint style="warning" %}
|
||
Note that entitlements starting with **`com.apple`** are not available to third-parties, only Apple can grant them.
|
||
{% endhint %}
|
||
|
||
## High
|
||
|
||
### `com.apple.rootless.install.heritable`
|
||
|
||
The entitlement **`com.apple.rootless.install.heritable`** allows to **bypass SIP**. Check [this for more info](macos-sip.md#com.apple.rootless.install.heritable).
|
||
|
||
### **`com.apple.rootless.install`**
|
||
|
||
The entitlement **`com.apple.rootless.install`** allows to **bypass SIP**. Check[ this for more info](macos-sip.md#com.apple.rootless.install).
|
||
|
||
### **`com.apple.system-task-ports` (previously called `task_for_pid-allow`)**
|
||
|
||
This entitlement allows to get the **task port for any** process, except the kernel. Check [**this for more info**](../mac-os-architecture/macos-ipc-inter-process-communication/).
|
||
|
||
### `com.apple.security.get-task-allow`
|
||
|
||
This entitlement allows other processes with the **`com.apple.security.cs.debugger`** entitlement to get the task port of the process run by the binary with this entitlement and **inject code on it**. Check [**this for more info**](../mac-os-architecture/macos-ipc-inter-process-communication/).
|
||
|
||
### `com.apple.security.cs.debugger`
|
||
|
||
Apps with the Debugging Tool Entitlement can call `task_for_pid()` to retrieve a valid task port for unsigned and third-party apps with the `Get Task Allow` entitlement set to `true`. However, even with the debugging tool entitlement, a debugger **can’t get the task ports** of processes that **don’t have the `Get Task Allow` entitlement**, and that are therefore protected by System Integrity Protection. Check [**this for more info**](https://developer.apple.com/documentation/bundleresources/entitlements/com\_apple\_security\_cs\_debugger).
|
||
|
||
### `com.apple.security.cs.disable-library-validation`
|
||
|
||
This entitlement allows to **load frameworks, plug-ins, or libraries without being either signed by Apple or signed with the same Team ID** as the main executable, so an attacker could abuse some arbitrary library load to inject code. Check [**this for more info**](https://developer.apple.com/documentation/bundleresources/entitlements/com\_apple\_security\_cs\_disable-library-validation).
|
||
|
||
### `com.apple.private.security.clear-library-validation`
|
||
|
||
This entitlement is very similar to **`com.apple.security.cs.disable-library-validation`** but **instead** of **directly disabling** library validation, it allows the process to **call a `csops` system call to disable it**.\
|
||
Check [**this for more info**](https://theevilbit.github.io/posts/com.apple.private.security.clear-library-validation/).
|
||
|
||
### `com.apple.security.cs.allow-dyld-environment-variables`
|
||
|
||
This entitlement allows to **use DYLD environment variables** that could be used to inject libraries and code. Check [**this for more info**](https://developer.apple.com/documentation/bundleresources/entitlements/com\_apple\_security\_cs\_allow-dyld-environment-variables).
|
||
|
||
### `com.apple.private.tcc.manager` and `com.apple.rootless.storage`.`TCC`
|
||
|
||
[**According to this blog**](https://objective-see.org/blog/blog\_0x4C.html), these entitlements allows to **modify** the **TCC** database.
|
||
|
||
### **`system.install.apple-software`** and **`system.install.apple-software.standar-user`**
|
||
|
||
These entitlements allows to **install software without asking for permissions** to the user, which can be helpful for a **privilege escalation**.
|
||
|
||
### `com.apple.private.security.kext-management`
|
||
|
||
Entitlement needed to ask the **kernel to load a kernel extension**.
|
||
|
||
### **`com.apple.private.icloud-account-access`**
|
||
|
||
The entitlement **`com.apple.private.icloud-account-access`** it's possible to communicate with **`com.apple.iCloudHelper`** XPC service which will **provide iCloud tokens**.
|
||
|
||
**iMovie** and **Garageband** had this entitlement.
|
||
|
||
For more **information** about the exploit to **get icloud tokens** from that entitlement check the talk: [**#OBTS v5.0: "What Happens on your Mac, Stays on Apple's iCloud?!" - Wojciech Regula**](https://www.youtube.com/watch?v=\_6e2LhmxVc0)
|
||
|
||
### `com.apple.private.tcc.manager.check-by-audit-token`
|
||
|
||
TODO: I don't know what this allows to do
|
||
|
||
### `com.apple.private.apfs.revert-to-snapshot`
|
||
|
||
TODO: In [**this report**](https://jhftss.github.io/The-Nightmare-of-Apple-OTA-Update/) **is mentioned that this could be used to** update the SSV-protected contents after a reboot. If you know how it send a PR please!
|
||
|
||
### `com.apple.private.apfs.create-sealed-snapshot`
|
||
|
||
TODO: In [**this report**](https://jhftss.github.io/The-Nightmare-of-Apple-OTA-Update/) **is mentioned that this could be used to** update the SSV-protected contents after a reboot. If you know how it send a PR please!
|
||
|
||
### `keychain-access-groups`
|
||
|
||
This entitlement list **keychain** groups the application has access to:
|
||
|
||
```xml
|
||
<key>keychain-access-groups</key>
|
||
<array>
|
||
<string>ichat</string>
|
||
<string>apple</string>
|
||
<string>appleaccount</string>
|
||
<string>InternetAccounts</string>
|
||
<string>IMCore</string>
|
||
</array>
|
||
```
|
||
|
||
### **`kTCCServiceSystemPolicyAllFiles`**
|
||
|
||
Gives **Full Disk Access** permissions, one of the TCC highest permissions you can have.
|
||
|
||
### **`kTCCServiceAppleEvents`**
|
||
|
||
Allows the app to send events to other applications that are commonly used for **automating tasks**. Controlling other apps, it can abuse the permissions granted to these other apps.
|
||
|
||
### **`kTCCServiceSystemPolicySysAdminFiles`**
|
||
|
||
Allows to **change** the **`NFSHomeDirectory`** attribute of a user that changes his home folder and therefore allows to **bypass TCC**.
|
||
|
||
### **`kTCCServiceSystemPolicyAppBundles`**
|
||
|
||
Allow to modify files inside apps bundle (inside app.app), which is **disallowed by default**.

|
||
|
||
## Medium
|
||
|
||
### `com.apple.security.cs.allow-jit`
|
||
|
||
This entitlement allows to **create memory that is writable and executable** by passing the `MAP_JIT` flag to the `mmap()` system function. Check [**this for more info**](https://developer.apple.com/documentation/bundleresources/entitlements/com\_apple\_security\_cs\_allow-jit).
|
||
|
||
### `com.apple.security.cs.allow-unsigned-executable-memory`
|
||
|
||
This entitlement allows to **override or patch C code**, use the long-deprecated **`NSCreateObjectFileImageFromMemory`** (which is fundamentally insecure), or use the **DVDPlayback** framework. Check [**this for more info**](https://developer.apple.com/documentation/bundleresources/entitlements/com\_apple\_security\_cs\_allow-unsigned-executable-memory).
|
||
|
||
{% hint style="danger" %}
|
||
Including this entitlement exposes your app to common vulnerabilities in memory-unsafe code languages. Carefully consider whether your app needs this exception.
|
||
{% endhint %}
|
||
|
||
### `com.apple.security.cs.disable-executable-page-protection`
|
||
|
||
This entitlement allows to **modify sections of its own executable files** on disk to forcefully exit. Check [**this for more info**](https://developer.apple.com/documentation/bundleresources/entitlements/com\_apple\_security\_cs\_disable-executable-page-protection).
|
||
|
||
{% hint style="danger" %}
|
||
The Disable Executable Memory Protection Entitlement is an extreme entitlement that removes a fundamental security protection from your app, making it possible for an attacker to rewrite your app’s executable code without detection. Prefer narrower entitlements if possible.
|
||
{% endhint %}
|
||
|
||
### `com.apple.security.cs.allow-relative-library-loads`
|
||
|
||
TODO
|
||
|
||
### `kTCCServiceAll`
|
||
|
||
According to this blogpost, this TCC permission usually found in the form:
|
||
|
||
```
|
||
[Key] com.apple.private.tcc.allow-prompting
|
||
[Value]
|
||
[Array]
|
||
[String] kTCCServiceAll
|
||
```
|
||
|
||
Allow the process to **ask for all the TCC permissions**.
