CVE-2023-46033: Wireless N 300 ADSL2+ Modem Router DSL-2750U

Almost 10 years ago, researchers identified and presented the "triple handshake" man-in-the-middle attack in TLS 1.2. The vulnerability breaks confidentiality of the connection and allows an attacker to impersonate a client. In response, RFC 7627 introduced the Extended Master Secret Extension for TLS 1.2 in September 2015, which prevents the attack.

All major TLS libraries now support the Extended Master Secret (EMS) and enable it by default. Unfortunately, many older operating systems and embedded devices such as WiFi access points and home routers do not support it. For example, Red Hat

Almost 10 years ago, researchers identified and presented the "triple handshake" man-in-the-middle attack in TLS 1.2. The vulnerability breaks confidentiality of the connection and allows an attacker to impersonate a client. In response, RFC 7627 introduced the Extended Master Secret Extension for TLS 1.2 in September 2015, which prevents the attack.

All major TLS libraries now support the Extended Master Secret (EMS) and enable it by default. Unfortunately, many older operating systems and embedded devices such as WiFi access points and home routers do not support it. For example, Red Hat Enterprise Linux (RHEL) 7 ships OpenSSL 1.0, which supports neither TLS 1.3, nor the EMS extension in TLS 1.2.

**NIST requires EMS after May 16, 2023**

The US National Institute of Standards and Technology (NIST) defines the set of standards required for FIPS 140-3 certification, which many of Red Hat’s customers in the public sector require. In May 2022, NIST decided that "\[a\] new validation, \[…\] submitted more than one year after \[May 2022\] shall use the extended master secret in the TLS 1.2 KDF." (see FIPS 140-3 IG, section D.Q.) Any cryptographic module submitted for validation or re-validation after May 16th, 2023 must use the Extended Master Secret to be compliant.

**RHEL's submissions for FIPS 140-3 validation**

The Red Hat Crypto Team submitted the OpenSSL and NSS modules for RHEL 9.0 for validation on May 15, 2023. They were therefore exempt from this requirement. RHEL 9.0 was the first release submitted for certification against NIST’s new version of the FIPS 140 standards, FIPS 140-3. Submissions for the older standard 140-2 are no longer accepted after September 22, 2021. Due to the large number of changes required to make RHEL comply with FIPS 140-3 and the long queue of validations, this submission only happened after RHEL 9.2 was generally available on May 10, 2023. Therefore, certification of the modules shipped in RHEL 9.2 at general availability was not possible without further changes.

From this position, none of the options are particularly appealing.

**Using an explicit FIPS indicator**

A feasible option might have been what NIST's Implementation Guidance for FIPS 140-3 calls a "Security Service Indicator" in section 2.4.C: a separate function that applications can call to verify whether the performed operation was compliant. In this case, the function could have returned true if the TLS connection used the Extended Master Secret, and false otherwise. This is enough to pass certification, but requires that all applications that care about FIPS compliance start checking this indicator. In practice, hardly any applications would do this, and systems would continue to silently make and accept TLS connections without EMS. This satisfies the letter of the requirements but ignores their spirit. NIST clearly wanted to declare TLS connections that do not use EMS non-compliant. We feel that working around this intent silently is not the right thing to do.

**Enforce EMS in z-stream**

The second possibility is changing the behavior of the cryptographic modules in 9.2 z-stream during the lifetime of RHEL 9.2. The obvious downside is that systems will no longer be able to establish TLS connections without EMS, where such connections did work with RHEL 9.2 when it was initially released. However, this change only affects users running systems in FIPS mode, who presumably use this mode because they need to comply with FIPS regulations.

OpenSSL was the first cryptographic library to implement the change in RHSA-2023:3722. GnuTLS followed, and NSS will soon complete the list of cryptographic libraries that implement TLS key derivation. At the same time, an article in the customer portal explains the new requirement.

Of course, it would have been better if this change had landed in RHEL 9.3 or later, or ideally, only in RHEL 10. Unfortunately, conflicting timelines between the Red Hat Enterprise Linux release schedule and government requirements do not always allow for delaying such changes.

**Connecting to old servers**

If you need to communicate with endpoints that do not support the TLS Extended Master Secret from a RHEL 9.2 system in FIPS mode, be aware that this is not FIPS-compliant. If that risk is acceptable to you and your auditors, a recent crypto-policies update now offers a workaround. The NO-ENFORCE-EMS policy module relaxes the enforcement of the requirement and allows connections without protections against the triple handshake attack. Executing

$> update-crypto-policies --set FIPS:NO-ENFORCE-EMS

enables the policy module.

For more information about Red Hat Enterprise Linux’s compliance with government standards, see the Compliance Activities and Government Standards page on the customer portal. The Security Hardening documentation has additional information about system-wide cryptographic policies.

Believe it or not, the internet is now over half a century old. Of course, it has really…
This is a post from HackRead.com Read the original post: Is It Possible to Delete Yourself From the Internet Altogether?

Believe it or not, the internet is now over half a century old. Of course, it has really come in leaps and bounds in the last few decades, with **technological advances** and innovations making global communication easier than ever.

The explosion of apps, social media platforms and e-commerce portals that this has instigated has encouraged us to part with more and more of our personal information… but it appears that we may have finally reached a tipping point in this regard. In **a recent survey**, over 80% of respondents said they were concerned about how their online data is used by others.

For that reason, an increasing number of internet users are contemplating extricating themselves from the World Wide Web altogether. But is such a thing even possible? We’ll investigate the topic in greater detail below.

****Can you delete yourself from the internet?****

Technically speaking, it’s not possible to remove all traces of yourself and your online activity from the internet with 100% certainty. That’s because most people have been interacting with the net on a daily basis for many years and over this time, they have created an extensive digital footprint which it’s extremely challenging to eradicate.

Having said that, there are plenty of steps you can take to reduce your online exposure and limit the amount of personal information that is shared with others online. This will reduce the likelihood of unwanted outcomes, such as spam messages, unsolicited robocalls and targeted ads, as well as more concerning eventualities such as fraud, identity theft and scams.

****How can I remove existing traces of personal information?****

Every time you’ve ever interacted with a website, app or digital service provider – and that includes everything from making an e-commerce purchase to signing up for an email newsletter to posting content on social media platforms – you’ve (perhaps inadvertently, perhaps intentionally) shared information about yourself with the world. 

To start, you can **remove your personal info from Google Search** and then go through other steps such as opting out of data brokerage agreements, contacting individual service providers to request the removal of your data and deleting any old or obsolete accounts that you no longer use. This can take a significant investment of time and effort, though there are third-party companies which will lend you their expertise for a nominal fee.

****Is it possible to use the internet anonymously in the future?****

So now that you’ve cleaned up your online presence as best as possible, can you continue using the internet without leaving further footprints? Yes and no. While your online activity can always be logged in some regard, you can alter your approach to minimize the amount of personal information you leave behind going forward.

This will involve such steps as installing and activating a **VPN** on your device to mask its location and encrypt all information sent using it, as well as refraining from logging on to public Wi-Fi networks and using browsers which offer greater protection. You can also tweak the privacy settings on your accounts to maintain control of your data more comprehensively.

Given the nature of the beast, it’s all but impossible to remove yourself from the internet altogether. However, with an investment of time, effort and perhaps money, you can reduce your online presence quite substantially.

Unchecked user input length in /subsys/net/l2/wifi/wifi_shell.c can cause buffer overflows.

**Summary**

I spotted two instances of user input with unchecked length at the following locations in the Zephyr WiFi shell module source code:  
https://github.com/zephyrproject-rtos/zephyr/blob/main/subsys/net/l2/wifi/wifi\_shell.c#L334-L335  
https://github.com/zephyrproject-rtos/zephyr/blob/main/subsys/net/l2/wifi/wifi\_shell.c#L355-L356

**Details**

Unchecked user input length in /subsys/net/l2/wifi/wifi\_shell.c:

static int \_\_wifi\_args\_to\_params(size\_t argc, char \*argv\[\],
				struct wifi\_connect\_req\_params \*params)
{
	char \*endptr;
	int idx \= 1;

	if (argc < 1) {
		return \-EINVAL;
	}

	/\* SSID \*/
	params\->ssid \= argv\[0\]; /\* VULN: unchecked length (should be max 32) \*/
	params\->ssid\_length \= strlen(params\->ssid);

	/\* Channel (optional) \*/
	if ((idx < argc) && (strlen(argv\[idx\]) <= 3)) {
...

	/\* PSK (optional) \*/
	if (idx < argc) {
		params\->psk \= argv\[idx\]; /\* VULN: unchecked length (should be min 8, max 64) \*/
		params\->psk\_length \= strlen(argv\[idx\]);
		/\* Defaults \*/
		params\->security \= WIFI\_SECURITY\_TYPE\_PSK;
		params\->mfp \= WIFI\_MFP\_OPTIONAL;
		idx++;

**PoC**

I haven't tried to reproduce these potential vulnerabilities against a live install of the Zephyr OS.

**Impact**

The unchecked inputs may cause buffer overflows in other locations, the impact of which could range from denial of service to arbitrary code execution.

**Patches**

This has been fixed in:

*   main (v3.5 development cycle) #60537
*   3.4 #61383
