Hello folks,
I realized that printing some information on log files could violate PCI
CSS (Payment Card Industry Data Security Standard) depends on how they
configure the system, and how to use the log file. If I understood
correctly, we're printing card holder's information including credit
card number, expiration and CVV num in plain text on log file.
If we don't print out on the log at all on the live site, that would
solve the problem. But if there is a person who wasn't aware of that
fact, he might accidentally violate the PCI DSS compliance. For
example, let's say there is a person who keeps the log to be printed on
the live site. And for some reason, he downloaded log file to his local
computer and kept unsafe location, or passed to someone else to let them
take a look that log file for asking help. Then I believe he is
violating the PCI CSS compliance accidentally.
Code involved 1:
[PayflowPro.java:166]
if (Debug.verboseOn()) Debug.logVerbose("Sending to Verisign: " +
params.toString(), module);
Logs which is being printed:
[Datetime] (TP-Processor70) [ PayflowPro.java:166:INFO ] Sending
to Verisign: PARTNER=verisign&VENDOR=[Company
]&USER=[UserID]&PWD=[Password]&COMMENT1=[Order ID]&PONUM=[PO Order Id]
&CUSTCODE=[Customer's code]&TRXTYPE=[]&TENDER=[]&CVV2=*[CVV
number*]&AMT=[Amount]&ACCT=*[16 digit credit card number in plain
text]*&FIRSTNAME=[Cardholder's firstname]&LASTNAME=[Card holder's last
name]&COMMENT2=[]&EXPDATE=*[expiration date]*&STREET=[Card holder's
address&ZIP=[card holder's zip code]
Code involved 2:
[RequestHandler.java:719]
if (Debug.infoOn()) Debug.logInfo("Sending redirect to: [" + url + "],
sessionId=" + UtilHttp.getSessionId(req), module);
=> I realized that credit card information is being printed from
different file as well (RequestHandler.java:719). I need to check what
service triggers RequestHandler.java:719 and passes credit card
information within url variable. But at least I noticed sometimes that
line in the log file contains credit card information in plain text as well.
PCI DSS involved:
7. Restrict access to cardholder data by business need-to-know
9. Restrict physical access to cardholder data

So, here is my questions & recommendation:
1. As we (at least I) want to keep log for in case, I think it's better
to not to print out credit card information to the log file. What do you
think? Do you think deleting that line is the best option?
2. If you guys think it's better to print out at least some information
to log file for some purpose, I believe it's better to print out in
encrypted format rather than in plain text. Otherwise we can print out
last 4 digit or first 4 digit, not entire number.
3. Do you know what triggers RequestHander to print out credit card
information?
4. Is there any other file you can think of which likely print out
credit card information to log file?
Hope it would be helpful for security improvement for myself and someone
else who may use ofbiz on the live site.
Thanks you for reading.
