Historical advisories reported information-disclosure and denial-of-service flaws in legacy versions of Cart32, a shopping-cart application. Xato Network Security said a request to c32web.exe/ShowProgress could drive processor use to 100% on affected Win32 servers, while separate reports described server-detail exposure through /expdate. These reports concern specific versions and dates; they do not establish that Cart32 is still supported, available, or exposed on modern systems.
What the Cart32 advisories reported
The issues were not one single vulnerability. Reports from 2000 described different effects, request paths, and version ranges. In particular, Xato’s November 9, 2000 advisory covered multiple information-leakage issues and a denial-of-service issue affecting Win32-based servers using Cart32 v3.5 and below. Its wording does not mean every issue affected every version in the same way.
| Issue | Reported behavior | Version or system named by the source | Date and remediation stated |
|---|---|---|---|
| Information leakage and physical-path disclosure | Xato described URLs that revealed physical server paths. | Win32-based servers using Cart32 v3.5 and below. | Xato advisory, November 9, 2000; it said version 3.5a addressed most of the listed issues. Xato Network Security advisory |
Denial of service through ShowProgress |
A request to c32web.exe/ShowProgress could drive processor use to 100%, according to the advisory. |
Win32-based servers using Cart32 v3.5 and below. | Xato advisory, November 9, 2000; 3.5a addressed most, not necessarily all, listed issues. Xato Network Security advisory |
Debug-page information leak through /expdate |
Juniper’s historical signature says the request could return an error followed by a debugging page showing server variables and the administration directory, and possibly contents of cgi-bin. |
Cart32.exe v2.6 and v3.0, as identified on Juniper’s signature page. | Signature released January 22, 2004; it references CVE-2000-0430. The cited entry does not state a remediation. Juniper threat-signature description |
How the ShowProgress denial-of-service report works
Xato described a request to c32web.exe/ShowProgress as capable of making processor usage jump to 100%. That figure is the advisory’s description of the impact, not a current benchmark or a result independently reproduced here. The report’s scope is legacy Win32 servers running Cart32 v3.5 and below; it should not be generalized to all Cart32 installations or current systems.
The availability impact is different from information leakage: the former could consume processor capacity, while the latter could expose server details. Xato’s advisory grouped multiple reported flaws together, so the 3.5a statement should be read narrowly: it said that release fixed “most” of the issues it described, not all of them.
#1 Best Overall
What the /expdate information leak could expose
Juniper’s historical threat-signature description says that appending /expdate to a request for cart32.exe could trigger an error and then show a debugging page. The page could reveal server variables and the Cart32 administration directory, and might expose the contents of cgi-bin. Juniper identifies Cart32.exe v2.6 and v3.0 as vulnerable in this entry. Those version details are specific to Juniper’s description and should not be collapsed into Xato’s broader v3.5-and-below range.
Juniper’s signature was released January 22, 2004 and references CVE-2000-0430. A signature description documents a historical threat pattern; it does not establish how prevalent the flaw is today or whether an installation remains reachable.
Other vulnerabilities in Cart32’s historical record
Two additional records provide context but describe different flaws from the title’s information leak and denial-of-service reports.

- Hidden form fields and purchase data: The National Vulnerability Database describes CVE-2000-0136 as allowing remote modification of sensitive purchase information through hidden form fields. NVD assigns the historical record a CVSS v2 base score of 7.5 (HIGH); the record was published February 1, 2000 and was last modified June 16, 2026. The score belongs to this purchase-information issue, not to the ShowProgress denial-of-service report. NVD entry for CVE-2000-0136
- Backdoor password: CVE-2000-0429 records a backdoor password in Cart32 3.0 and earlier that could enable remote arbitrary command execution. This is a separate vulnerability, not another name for the information leak or DoS issue. NVD entry for CVE-2000-0429
What the historical mitigation guidance says
Xato’s November 9, 2000 advisory said Cart32 3.5a addressed most of the issues it listed. A separate joint advisory dated November 6, 2000 discussed a weakly protected administrator password and possible plaintext passwords in the Debug section of cart32.ini; it recommended Cart32 3.5a build 710 and securing Cart32 files. These are period-specific recommendations, not confirmation that the installers remain obtainable, supported, or suitable as a present-day security fix.

What these reports mean for a current Cart32 installation
The available historical sources do not establish whether Cart32 is still deployed or supported, whether version 3.5a or build 710 can still be obtained, or whether modern systems remain vulnerable. If you administer a system that may run Cart32, first identify the software and version from its installed files and deployment records, then determine whether it is reachable and what data or services it can access. Do not assume an old version number or historical patch recommendation proves that a system is safe today; seek a supported migration or security path from the responsible vendor or system owner.
