👿 Rogue DHCP Server

Quando un client entra in rete, accetta spesso la prima risposta DHCP ricevuta. Un server DHCP non autorizzato può assegnare gateway e DNS malevoli, intercettando il traffico e aprendo la strada a phishing, MITM e furto di credenziali.

Security Advisory: CVE-2025-70102 - NULL Pointer Dereference in dhcpcd parse_option

Summary
A crafted dhcpcd configuration input can trigger undefined behavior in the configuration parser by causing `parse_option()` to access a member through a NULL `struct dhcp_opt` pointer.

The issue is located in `src/if-options.c` in `parse_option()`. During parsing of malformed or unexpected option data, the lookup/parsing path can leave the local DHCP option pointer unset. The affected code then assumes the option pointer is valid and accesses embedded option metadata through it, which results in a NULL pointer member access at `src/if-options.c:1886`.

CWE:
CWE-758 - Reliance on Undefined, Unspecified, or Implementation-Defined Behavior

Affected Component:
```
src/if-options.c:1886
Function: parse_option()
```

Affected Product:
dhcpcd

Affected Version:
The issue was reproduced against dhcpcd commit:
```
2de751b3691642151a4fdc49e444d6b4dc364e98
```

Attack Conditions:
An attacker must cause dhcpcd to process a crafted configuration input that reaches the vulnerable option parsing path. The issue was reproduced in an instrumented fuzzing build of the dhcpcd configuration reader.

Impact:
The vulnerability causes undefined behavior and process termination under the sanitizer build, resulting in Denial of Service. No evidence of arbitrary code execution was observed in the local crash data.

Fix:
The issue was fixed in dhcpcd commit:
```
117742d755b591764036dd4218f314f748a3d2b7
```
The fix ensures that the pointed-to local DHCP option entry is non-NULL before it is dereferenced. Users should update to a dhcpcd build containing this commit or later.

Stampante non funziona su Windows 10 e 11: tutti i problemi e come risolverli

Wenn ich richtig sehe hat @cfhn heimlich still und leise die #DHCP26 angekündigt:

#DHCP ist ein kleines, gemütliches Event in Heilbronn, das @Habrok42 und ich gerne wegen der Menschen empfehlen.

The #DHCP server, running on the #OpenWRT router, assigned an internal IP to a client. However this IP was already used by a central NAS device. This situation is called an IP address conflict.

In our latest #tutorial we show where to find the current DHCP leases, how to create a static and remove an existing lease on @openwrt .

OMG, i thought things were supposed to get simpler as newer versions of software came out.

On the "Legacy" ISC #DHCP settings in #OPNSense, you could just type an IP address into the NTP text box.

In the "improved" version, which uses Kea DHCP instead, it will only accept "hex".

I assume this is just the #IPv6 address with no ":"s and loads of "0000"s (in my case), but some guidance would be helpful.... or just a fucking text box specifically for a IP address like the "legacy" version <sigh>.
