June Patch Tuesday digs into 67 bugs – Sophos Information

.Microsoft on Tuesday released 67 patches affecting 12 product households. Ten of the addressed points, 5 involving 365 and Workplace and one involving SharePoint, are thought-about by Microsoft to be of Critical severity, and 17 have a CVSS base rating of 8.0 or larger. One, an Vital-severity RCE in Home windows associated to WEBDAV (CVE-2025-33053), is recognized to be below energetic exploitation within the wild. A further Vital-severity SMB subject has been publicly disclosed, however shouldn’t be at the moment recognized to be below exploit. 

At patch time, 9 further CVEs are extra more likely to be exploited within the subsequent 30 days by the corporate’s estimation, not together with the WEBDAV subject talked about above. Numerous of this month’s points are amenable to direct detection by Sophos protections, and we embody info on those in a desk under. This most definitely consists of CVE-2025-33053, by which Sophos itself has taken a selected curiosity – and, apparently, vice versa.

Along with these patches, ten Adobe Reader fixes, 4 of them thought-about to be of Important severity, are included within the launch. These are listed in Appendix D under. That appendix additionally contains info on two Edge-related vulnerabilities and a Important-severity Energy Automate subject that was addressed earlier this month, in addition to restricted info on a Important-severity bug in Copilot for which an advisory was launched the next day (Wednesday). The periodically launched Servicing Stack updates are additionally out there.  

We’re as all the time together with on the finish of this put up further appendices itemizing all Microsoft’s patches sorted by severity, by predicted exploitability timeline and CVSS Base rating, and by product household; an appendix masking the advisory-style updates; and a breakout of the patches affecting the assorted Home windows Server platforms nonetheless in help.

Because it was mitigated previous to launch, we’re treating that info as advisory-only and don’t embody it on this month’s statistics. Likewise, the Copilot advisory launched on June 11 has a CVSS base rating of 9.3, however doesn’t determine into these tallies or charts.

Determine 1: A proportionally heavier-than-usual ten Important-severity patches had been launched in June,  although unusually six of these happen in 365, Workplace, or SharePoint fairly than the extra customary Home windows. (Two Edge updates coated this month will not be launched with full influence info and thus don’t seem on this chart; we’re additionally excluding the Energy Automate patch as mentioned above)

As is our customized for this record, CVEs that apply to a couple of product household are counted as soon as for every household they have an effect on. We be aware that CVE names don’t all the time replicate affected product households carefully. Particularly, some CVEs names within the Workplace household could point out merchandise that don’t seem within the record of merchandise affected by the CVE, and vice versa.

Determine 2: Twelve product households determine in Might’s Patch Tuesday launch; the Nuance medical-product household returns to the charts for a second month, this time addressing a spoofing subject in its Digital Engagement Platform 

Notable June updates 

Along with the problems mentioned above, a number of particular objects advantage consideration.  

CVE-2025-33053 — Net Distributed Authoring and Versioning (WebDAV) Distant Code Execution Vulnerability 

The one patched subject at the moment recognized to be below exploit within the wild is an Vital-severity flaw in Net Distributed Authoring and Versioning code, which has been underpinning a lot of the web for the reason that IE period. That’s the issue; this patch touches the MSHTML, EdgeHTML, and scripting platforms, that are all nonetheless supported. Because of this these Microsoft prospects at the moment taking Safety Solely updates want to put in the IE Cumulative updates to correctly guard towards this vulnerability – one thing right here for everybody, in different phrases. 

The adversaries exploiting that vulnerability apparently discovered Sophos protections vexing.  Endpoint safety scans new applications earlier than they run—however after launch, scanning drops off. Attackers exploit this by delivering applications with encrypted our bodies that evade static scanning and AI fashions. As soon as operating, the code decrypts itself, masses implants, and executes totally in reminiscence—by no means touching disk. 

Sophos counters this with Dynamic Shellcode Safety, which limits how a lot executable reminiscence a course of can allocate. That restriction breaks stealthy in-memory assaults, forcing adversaries to revert to noisier, extra detectable methods like distant injection—the place they’re a lot simpler to catch. 

 After that the attackers would have run into a number of extra Sophos layers of blacklist, antimalware signatures, and different defenses — however it’s fascinating to us to see ourselves mirrored in an adversary’s code as a very powerful nut to crack. In any case, we advocate as all the time that defenders prioritize higher-profile patches corresponding to this one. 

CVE-2025-33073 – Home windows SMB Consumer Elevation of Privilege Vulnerability 

It’s not recognized to be below energetic exploitation but, and Microsoft signifies that they suppose it’s much less more likely to be exploited throughout the subsequent 30 days, however this Vital-severity EoP is the one June CVE recognized to have been publicly disclosed to this point. The problem comes right down to improper entry controls, and it impacts all supported Home windows consumer and server variations. 

CVE-2025-47166 — Microsoft SharePoint Server Distant Code Execution Vulnerability 

After debuting in Might, “zcgonvh’s cat Vanilla” makes an instantaneous return look on the finder roster – that’s proper, the cat got here again the very subsequent Patch Tuesday. 

CVE-2025-32711 — M365 Copilot Data Disclosure Vulnerability 

Lastly, one CVE that was not launched within the Tuesday assortment, however merited the discharge of an advisory the next day: a Important-severity, CVSS-base 9.3, information-disclosure error that made it doable for an unauthorized attacker to make use of command injection to reveal info from the AI instrument. The vulnerability was responsibly disclosed to Microsoft and the corporate acknowledged early Wednesday that the patch is already pushed to prospects.  

Determine 3: As we wrap up the primary half of the 12 months, the proportion of Important-severity RCEs over the previous six months is eye-catching 

Determine 4: Evaluating first-half totals for 2024 and 2025, we see that the excessive variety of Important-severity RCEs stands out much more strongly when in comparison with the 12 months earlier than – 40, in contrast with simply 9 for the primary half of the 12 months earlier than. Just a few different traits stand out as properly, together with massive year-over-year will increase in info disclosure CVEs (44 in 1H24, 77 to this point in 2025) and denial of service points (34 in 1H24, 57 to this point in 2025) 

Sophos protections 

CVE-2025-33053 additionally has an relevant detection of be aware, Troj/UrlRun-B, along with the XSG signature famous above. 

As you may each month, when you don’t wish to wait to your system to tug down Microsoft’s updates itself, you may obtain them manually from the Home windows Replace Catalog web site. Run the winver.exe instrument to find out which construct of Home windows 10 or 11 you’re operating, then obtain the Cumulative Replace bundle to your particular system’s structure and construct quantity.
