| CVE | Vulnerability | CVSS | EPSS | Flags | Affected | Exposure | Published |
|---|---|---|---|---|---|---|---|
| CVE-2017-0199 | Remote Code Execution in Microsoft Office and WordPad via crafted document files CVE-2017-0199 is a remote code execution vulnerability in Microsoft Office and WordPad that stems from improper parsing of specially crafted files. Attackers trigger it by getting a user to open a malicious document, after which attacker-controlled code executes with the privileges of the logged-in user. Anyone running the affected Microsoft Office or WordPad software is exposed, and CISA notes the flaw has been leveraged in ransomware campaigns; no CVSS score is available in the source data. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2021-11-03, and EPSS assigns a 99.9% probability of exploitation within 30 days (100th percentile), indicating active, ongoing exploitation. Do: Apply Microsoft's security updates for Office and Windows per vendor instructions, as required by CISA's KEV catalog; the flaw was publicly reported as fixed in Microsoft's April 2017 security updates. Until patched, treat unsolicited Office documents and email attachments as high-risk, since exploitation requires a user to open a crafted file. Verify that all Office and WordPad installations across the estate—especially endpoints that handle untrusted documents—have received the update. | 7.8 | 100% | KEV ransomware PoC ×6 |
| masshundreds of millions of Office installations worldwide (exact count unknown) | |
| CVE-2017-11882 | Memory Corruption RCE in Microsoft Office via Legacy Equation Editor CVE-2017-11882 is a memory corruption vulnerability (CWE-119) in Microsoft Office, residing in the legacy Microsoft Equation Editor component (EQNEDT32.EXE), that allows remote code execution in the context of the current user. Attackers trigger it by persuading a user to open a crafted document, most commonly an RTF file or other Office document carrying a malicious embedded equation object, which overflows a buffer while the equation content is parsed. Successful exploitation lets the attacker run arbitrary code with the privileges of the signed-in user, a typical foothold for malware delivery and, per CISA, for ransomware operations. Any environment running affected Microsoft Office builds is exposed; the source data does not enumerate specific affected version ranges. The flaw is confirmed exploited in the wild: it was added to the CISA Known Exploited Vulnerabilities catalog on 2021-11-03 with known ransomware use and holds a 99.9% EPSS score (percentile 100), though the source data lists no public PoC. Do: Apply Microsoft's Office security updates (November 2017 or later) across all endpoints, prioritizing this KEV-listed flaw given its known ransomware use. On systems that cannot yet be patched, disable or unregister the legacy Equation Editor (EQNEDT32.EXE) and consider blocking or warning on RTF attachments as interim mitigations. Check for indicators of abuse such as EQNEDT32.EXE spawning unexpected child processes after document opens. | 7.8 | 100% | KEV ransomware PoC ×10 |

The nation-state threat actor known as SideWinder has been attributed to a new cyber espionage campaign targeting ports and maritime facilities in the Indian Ocean and Mediterranean Sea.
The BlackBerry Research and Intelligence Team, which discovered the activity, said targets of the spear-phishing campaign include countries like Pakistan, Egypt, Sri Lanka, Bangladesh, Myanmar, Nepal, and the Maldives.
SideWinder, which is also known by the names APT-C-17, Baby Elephant, Hardcore Nationalist, Leafperforator, Rattlesnake, and Razor Tiger, is assessed to be affiliated with India. It has been operational since 2012, often making use of spear-phishing as a vector to deliver malicious payloads that trigger the attack chains.
"SideWinder makes use of email spear-phishing, document exploitation and DLL side-loading techniques in an attempt to avoid detection and deliver targeted implants," the Canadian cybersecurity company said in an analysis published last week.
The latest set of attacks employ lures related to sexual harassment, employee termination, and salary cuts in order to negatively impact the recipients' emotional state and trick them into opening booby-trapped Microsoft Word documents.
Once the decoy file is opened, it leverages a known security flaw (CVE-2017-0199) to establish contact with a malicious domain that masquerades as Pakistan's Directorate General Ports and Shipping ("reports.dgps-govtpk[.]com") to retrieve an RTF file.
The RTF document, in turn, downloads a document that exploits CVE-2017-11882, another years-old security vulnerability in the Microsoft Office Equation Editor, with the goal of executing shellcode that's responsible for launching JavaScript code, but only after ensuring that the compromised system is legitimate and is of interest to the threat actor.
It's currently not known what's delivered by means of the JavaScript malware, although the end goal is likely to be intelligence gathering based on prior campaigns mounted by SideWinder.
"The SideWinder threat actor continues to improve its infrastructure for targeting victims in new regions," BlackBerry said. "The steady evolution of its network infrastructure and delivery payloads suggests that SideWinder will continue its attacks in the foreseeable future."
The disclosure comes as a suspected Russian-linked threat actor is targeting entities interested in Indian political affairs with a Go-based remote access trojan (RAT) that's delivered via a .NET loader launched from Windows shortcut (LNK) files disguised as Office documents. The activity has been codenamed Operation ShadowCat.
