All C-language CGIs should now support CSP2 in browser to stop major forms of XSS javascript injection. Javascript on pages is gathered together, and then emitted in a single script block at the end with a nonce that tells the browser, this is js that we generated instead of being injected by a hacker. Both inline script from script blocks and inline js event handlers had to be pulled out and separated. You will not see js sprinkled through-out the page now. Older browsers that support CSP1 or that do not understand CSP at all will still work, just without protection. External js libraries loaded at runtime need to be added to the CSP policy header in src/lib/htmshell.c. diff --git src/hg/hgc/mafClick.c src/hg/hgc/mafClick.c index 02128cc..d7a0b25 100644 --- src/hg/hgc/mafClick.c +++ src/hg/hgc/mafClick.c @@ -1,815 +1,815 @@ /* Handle details pages for maf tracks and axt tracks. */ /* Copyright (C) 2013 The Regents of the University of California * See README in this or parent directory for licensing information. */ #include "common.h" #include "hash.h" #include "linefile.h" #include "hgc.h" #include "maf.h" #include "obscure.h" #include "cheapcgi.h" #include "genePred.h" #include "botDelay.h" #include "hgMaf.h" #include "hui.h" #include "hCommon.h" #include "hubConnect.h" #define ADDEXONCAPITAL /* Javascript to help make a selection from a drop-down * go back to the server. */ -static char *autoSubmit = "onchange=\"document.gpForm.submit();\""; +static char *autoSubmit = "document.gpForm.submit();"; static void blueCapWrite(FILE *f, char *s, int size, char *r) /* Write capital letters in blue. */ { boolean isBlue = FALSE; int i; for (i=0; i<size; ++i) { if (r!=NULL && s[i]==r[i]) fprintf(f, "."); else { char c = s[i]; if (isupper(c)) { if (!isBlue) { fprintf(f, "<span style='color:#0000FF;'>"); isBlue = TRUE; } } else if (islower(c)) { if (isBlue) { fprintf(f, "</span>"); isBlue = FALSE; } } fprintf(f, "%c", c); } } if (isBlue) fprintf(f, "</span>"); } void initSummaryLine(char *summaryLine, int size, int val) /* Fill summary line with stars and null terminate */ { int i; for (i = 0; i < size; i++) summaryLine[i] = val; summaryLine[i] = 0; } void updateSummaryLine(char *summaryLine, char *referenceText, char *alignText, int size) /* Blank out columns in the summary line where this alignment * differs from the reference */ { int i; for (i=0; i<size; i++) { if (alignText[i] != referenceText[i]) summaryLine[i] = ' '; } } void mafPrettyOut(FILE *f, struct mafAli *maf, int lineSize, boolean onlyDiff, int blockNo) { int ii, ch; int srcChars = 0; struct mafComp *mc; int lineStart, lineEnd; char *summaryLine = needMem(lineSize+1); char *referenceText; int startChars, sizeChars, srcSizeChars; boolean haveInserts = FALSE; struct mafComp *masterMc = maf->components; startChars = sizeChars = srcSizeChars = 0; for (mc = maf->components; mc != NULL; mc = mc->next) { /* Figure out length of source (species) field. */ /*if (mc->size != 0)*/ { char dbOnly[128]; int len; char *org; memset(dbOnly, 0, sizeof(dbOnly)); safef(dbOnly, sizeof(dbOnly), "%s", mc->src); chopPrefix(dbOnly); if ((org = hOrganism(dbOnly)) == NULL) len = strlen(dbOnly); else len = strlen(org); if (srcChars < len) srcChars = len; len = digitsBaseTen(mc->start); if (startChars < len) startChars = len; len = digitsBaseTen(mc->size); if (sizeChars < len) sizeChars = len; len = digitsBaseTen(mc->srcSize); if (srcSizeChars < len) srcSizeChars = len; if (mc->text && (mc->rightStatus == MAF_INSERT_STATUS) && (masterMc->start + masterMc->size < winEnd)) haveInserts = TRUE; #ifdef REVERSESTRAND /* complement bases if hgTracks is on reverse strand */ if (mc->size && cartCgiUsualBoolean(cart, COMPLEMENT_BASES_VAR, FALSE)) complement(mc->text, maf->textSize); #endif } } /* first sequence in the alignment */ referenceText = maf->components->text; for (lineStart = 0; lineStart < maf->textSize; lineStart = lineEnd) { int size; lineEnd = lineStart + lineSize; if (lineEnd >= maf->textSize) lineEnd = maf->textSize; size = lineEnd - lineStart; initSummaryLine(summaryLine, size, '*'); for (mc = maf->components; mc != NULL; mc = mc->next) { char dbOnly[128], *chrom; int s = mc->start; int e = s + mc->size; char *org; char *revComp = ""; char strand = mc->strand; struct dyString *dy = newDyString(512); #ifdef REVERSESTRAND if (cartCgiUsualBoolean(cart, COMPLEMENT_BASES_VAR, FALSE)) strand = (strand == '+') ?
